The Hidden Revenue Stream Most Resellers Ignore
If you're spending serious money on stock — £5,000, £10,000, £20,000+ per month across retailers — you're almost certainly doing it on a debit card or a basic credit card that earns you nothing. That's money you're leaving on the table every single month.
Rewards credit cards earn you points on every purchase. Those points can be converted into cash. For resellers who spend heavily on inventory, this creates a genuine third revenue stream on top of cashback and resale profits — and it takes zero extra effort once set up.
This guide explains how it works, which cards to use, and how to turn accumulated points into actual money in your bank account.
How Credit Card Points Work for Resellers
Rewards credit cards give you points for every pound you spend. The rate varies by card — typically 1 point per £1 spent, sometimes more on specific spending categories. These points accumulate in your card's rewards programme and can be redeemed for various things: flights, hotel stays, gift cards, or — most relevantly for resellers — cash.
The key insight is that your stock purchases are your single biggest expense. If you're spending £10,000/month buying inventory from retailers and wholesalers, that's 10,000+ points per month accumulating automatically. Over a year, that's 120,000+ points sitting in your account — and depending on how you cash them out, that could be worth £500–£1,500+ in real money.
Which Cards UK Resellers Actually Use
American Express (Amex)
American Express is the most popular rewards card among UK resellers, and for good reason. Their Membership Rewards programme earns 1 point per £1 spent (more on some cards), and the points are flexible — transferable to airlines, hotels, or cashable through third-party services.
The main cards to look at:
- Amex Gold — strong earn rate, annual fee but offset by statement credits. Good all-rounder for resellers with moderate spend
- Amex Platinum — higher earn rate on certain categories, premium perks, but significant annual fee. Only worth it at very high spend levels
- Amex Preferred Rewards Gold — earns Membership Rewards points with a solid welcome bonus
The catch with Amex: not all UK retailers accept it. Most major online retailers do (Amazon, Argos, etc.), but some smaller shops and wholesalers don't. You'll likely need a Visa or Mastercard as backup.
Capital On Tap
Capital On Tap is a business credit card designed specifically for small businesses. It earns 1% cashback or reward points on all spending, with no personal guarantee required on lower credit limits. It's particularly popular among resellers because:
- Application is quick and based on business revenue, not personal income
- Higher credit limits available as your business grows
- Points or cashback on every transaction, including wholesale purchases
- Accepted more widely than Amex (it's a Visa)
Other Options
- Barclaycard Avios — earns Avios points which can be cashed out via various methods
- Chase UK — 1% cashback on all spending for the first year. Simple, no points to manage
- HSBC Rewards — points programme with cashback redemption options
The best card for you depends on your spend level, which retailers you buy from most, and whether you prefer simple cashback or a points programme with potentially higher value.
Turning Points Into Cash
Here's where it gets interesting for resellers. Credit card companies offer their own redemption options for points, but the value per point through their standard channels is often poor. Redeeming Amex points for statement credit, for example, gives you significantly less value per point than other methods.
Points Buying Services
Services that buy your accumulated points and pay you cash — directly to your bank account or via crypto. The process is simple:
- You get a quote for your points (free, no obligation)
- If you accept, you transfer the points from your card's rewards programme to the buyer
- They pay you within hours — typically via bank transfer
This consistently delivers better value per point than redeeming through the credit card company's own channels. For Amex Membership Rewards and Capital On Tap points specifically, WeBuyMiles is the service our community uses — they've purchased over 10 million miles in the past 6 months, with cash payouts typically arriving within 60 minutes of accepting the offer.
How the Maths Works
Let's run a realistic scenario:
- You spend £20,000/month on stock using an Amex card
- That earns you 20,000 Membership Rewards points per month
- Over 6 months, you've accumulated 120,000 points
- A points buying service offers you a competitive rate per point
- You cash out and receive a lump sum in your bank within the hour
- Reinvest that cash into more stock — or keep it as pure profit
The exact value per point varies based on market rates and which programme you're cashing out from. But the principle is consistent: points that would otherwise sit unused (or be redeemed at poor rates through the card company) get converted into working capital.
Setting Up the Full Stack
Here's the complete optimised payment and rewards setup for a UK reseller:
Step 1: Get the Right Card
Apply for a rewards credit card that matches your spend level and the retailers you buy from. Amex for maximum points earn rate (where accepted), Capital On Tap for wider acceptance and business-specific features.
Step 2: Use It for All Stock Purchases
Put every business purchase on the rewards card — stock, packaging, tools, subscriptions. Every pound spent earns points. Set up a direct debit to pay the full balance monthly so you never carry a balance.
Step 3: Stack With Cashback and Discount Tools
Before every purchase, activate TopCashback for referral cashback, then let Coupert scan for discount codes at checkout. You're now earning points on the card, cashback through TopCashback, and potentially saving with a discount code — all on the same transaction.
Step 4: Cash Out Points Periodically
Once you've accumulated a meaningful number of points (every 3–6 months works well), get a quote from a points buying service and cash out. The cash goes back into your business or straight to your pocket.
Who This Works For
This strategy scales with your spending. The more you spend on stock, the more points you earn, and the more cash you can extract.
- Spending £2,000–£5,000/month — worth setting up, but the annual return will be modest (£200–£500). Still free money for zero effort
- Spending £5,000–£15,000/month — meaningful returns (£500–£1,500+/year). Enough to cover a tool subscription, a few months of accounting fees, or a chunk of inventory
- Spending £15,000+/month — significant returns. At this level, the points cashout becomes a genuine line item in your business financials
If you're spending less than £2,000/month on stock, the rewards from points alone are modest. But combined with cashback and discount codes, even lower-volume resellers benefit from having the full stack in place.
Building the Complete Margin Optimisation System
This post is the final piece of a three-part margin optimisation strategy:
- Cashback on purchases — earn money back via TopCashback on every stock purchase
- Browser extensions — automatic discount codes (Coupert) + price tracking (Keepa) + research tools
- Credit card points → cash — earn points on the payment itself, then convert to money
Each layer is small individually. Combined across hundreds of transactions per year, they add thousands to your bottom line. These aren't growth strategies — they're efficiency strategies. They improve your margins on purchases you're already making, without changing what you buy or sell.
For the growth side — knowing what to buy, when to buy it, and where to sell it — that's where ResellRadar's real-time intelligence and community come in. Optimise your costs with the tools above. Maximise your revenue with the right products. That's how you build a reselling business that actually scales.
