How do people actually make money reselling Pokémon cards?

By buying well (collections, bulk and lots below market), turning stock over efficiently, and knowing their real profit after eBay fees, postage and time. The margin comes from good sourcing and good decisions, not just from rare cards.

Do I need to register as a business to sell Pokémon cards in the UK?

If you're buying to sell on for profit, that's trading and may be taxable, there's a trading allowance to be aware of, and selling off a personal collection is treated differently. Check HMRC guidance or an accountant for your situation; this is not tax advice.

How many cards a month should I sell to go full-time?

There's no fixed number, it depends on your average profit per card and per hour. Measure profit-per-hour first; going full-time makes sense when your throughput and margin reliably cover your income needs.

What's the biggest mistake beginners make?

Not counting the real costs. Listing low-value cards that lose money after fees, postage and time, and never measuring actual profit, so they repeat their least profitable activity because it feels busy.

How to run a Pokémon card-selling business in the UK

The difference between a hobby and a business is discipline: knowing your profit-per-hour, running a real inventory system, sourcing deliberately, and keeping clean records. Do those four things and reselling scales; skip them and it quietly eats your time for little return.

Profit-per-hour: the number that matters

Revenue flatters you; profit tells the truth. Take your sale price, subtract what you paid for the card, eBay's fees, postage and packaging, and then divide the profit by the time it took to price, list, pack and post. That's profit-per-hour, and it's the number that should decide how you spend your evenings. Often it reveals that fiddly low-value singles pay far less than bundling, and that a good sourcing hour beats ten listing hours. See profit per hour for how to calculate and raise it.

Build a real inventory system

Past a hundred cards, memory stops scaling and cards get lost between "sold" and "shipped". Give every card a location (shelf, box, row, position) and a SKU, so you can find it in seconds and never mis-ship, there's a full walkthrough in building an inventory system. Then get disciplined about the split every reseller faces:

Singles: cards that clear a sensible net profit after fees and postage.
Bundles: mid-value cards grouped into themed lots to lift the order value above your floor.
Bulk: true commons sold by the 100 or 1,000 to clear space fast.

Getting that split right is where most of the profit, and most of the tedium, lives. See pricing & valuing for how to set the numbers.

Source deliberately

You make money when you buy, not just when you sell. Collections, bulk and job lots are where margin comes from, but only if you buy on the maths. Before you bid or offer, work backwards: estimated resale value minus fees, postage and your target margin gives the most you should pay. Buy above that and you've bought yourself a job, not a profit. Apply a condition-risk haircut on anything you can't inspect closely. See how to source cards to resell for where to find stock and the max-buy maths.

Pricing and fees discipline

Two habits protect your margin: always price from real sold comps, and always subtract eBay fees and postage before deciding a card is worth listing. A £3 card can be a loss once a stamp and fees come off, the discipline is refusing to list those and bulking them instead.

Scaling from side-hustle to full-time

Growth is a throughput problem, not a knowledge problem. As volume rises, the bottleneck becomes deciding, pricing, listing, packing and accounting, batch after batch. Systemise each step, measure profit-per-hour to cut the low-paying work, and only add volume you can fulfil accurately. Going full-time makes sense when your throughput and margin reliably cover your income needs, not when revenue looks big. There's a full guide to scaling from side hustle to full-time.

Records and tax (not advice)

Keep clean records from day one, what you paid, what you sold for, fees and postage. If you're buying to sell for profit in the UK, that's trading and may be taxable, with a trading allowance to be aware of; selling off a personal collection is treated differently. This is genuinely worth understanding, but check HMRC guidance or an accountant for your situation rather than a blog post. Good records make that painless, and make it easy to see which activity actually pays. Start with tax on selling Pokémon cards in the UK.

This whole loop, decide, price, store, ship, and know your real profit, is exactly what Curio was built to run, so the admin stops eating the hours you'd rather spend selling and sourcing.
