Ten mistakes every beginner makes on their first CD key purchase

I've been collecting this list for the past six months, since I started answering emails from people who lost money. Most stories sounded identical. Same mistakes, same losses, same later "if only I'd known". After 200 emails I could draw the typical patterns. Here are the ten most common, sorted from most universal to rarest.

Starting with the obvious, but don't skip them. Each of these cost someone real money.

Mistake 1: Picking a seller by price alone

Classic. You open GG2A, sort by price ascending, click the cheapest. Six dollars instead of thirty? Miracle. Seller has 34 ratings and 78 percent positive? Whatever, click through.

A week later the key doesn't work. The seller doesn't respond. The refund ticket in the store drags for two weeks. Money comes back but you lose the whole weekend trying. Just not worth it.

Rule: never below 98 percent positive ratings, minimum 500 ratings.

Mistake 2: Ignoring the key's region

"Steam Key Global Activation" in fine print. But in the description the seller adds "works with VPN from Turkey". Translation: it's NOT global. It's a Turkish key, and the seller is trying to convince you that you can bypass the regional check.

In 2025 this increasingly ends with a Steam account ban, not just a game ban. Even if the key activates today, in a month Valve might revoke the activation and put a warning on your account in the process.

Rule: GLOBAL, WORLDWIDE, EU, EMEA. Nothing else.

Mistake 3: Paying without protection

The cheapest payment option in stores is usually SEPA transfer or crypto. The store often gives an extra 5 to 8 percent discount for using these methods. Tempting.

Problem: in case of a dispute, you have no chargeback. Store refused the refund? Money gone. A Visa/Mastercard credit card costs you 1 to 2 percent commission but gives you a month for chargeback after first contacting the bank.

Rule: for expensive games (above 15 USD) always credit card or PayPal. Crypto and direct transfer only for small purchases where losing 5 bucks doesn't hurt.

Mistake 4: Activating on the main account without checking

You got the key, you go straight to Steam, type it in, the game adds. Two weeks later Valve revokes the key and leaves your account with a "warning". Three revoked keys in a year is a soft ban.

Rule: for expensive marketplace games, always test on a backup account first. Activate, check it launches, then transfer to main via Family Sharing or just leave it there.

Mistake 5: Ignoring hidden costs at checkout

Listed price: 14 USD. In cart: 17 USD. Where? Added: "instant delivery" fee (1 USD), buyer protection (1.50 USD, default checked), VAT (1 USD). The store knows this trick well, most people don't look at the final number, just click "buy".

Rule: always check the final amount in the cart. Uncheck default protections if you don't want them. Compare final cost, not listed cost.

Mistake 6: No price alerts on favorite games

You buy Cyberpunk for 30 USD on Wednesday. Saturday a promo drops on Eneba and the same game is 24. You feel cheated. All it took was setting a price alert that would have notified you.

Rule: on every game above 20 USD, a price alert in the comparator. On average a game drops 15 percent within 14 days of first check, so patience pays.

Mistake 7: Buying at launch instead of waiting 6 months

AAA launch: 70 USD. Six months later: 35 USD. A year later: 25 USD. The same product, in better shape (because all patches are in), at 30 percent of the price.

Rule: if you can wait 6 months without dying, wait. There's plenty to play in the meantime.

Mistake 8: Not reading the product name carefully

"Far Cry 6 Standard Edition" for 30 USD. "Far Cry 6 Gold Edition" for 34 USD. You skim, buy Standard, then notice in-game that you don't have the Season Pass, two DLCs, and the exclusive weapon. Adding them later costs 28 USD. Total spent: 58 USD, while Gold would have given you everything upfront for 34.

Rule: read the product name in full. Check whether it includes DLC. If you plan to play extensively, Gold/Deluxe/Complete edition is often worth it.

Mistake 9: Buying an account instead of a key because it's cheaper

"Steam Account Gift" for 12 USD, while a key costs 30. Wow, 18 dollars saved. You click. You get a login and password for someone else's account. You play for a week, the seller changes the password. You lose access to a game you never technically owned.

Rule: never buy anything labeled "Account", "Shared", "Family Account". This isn't savings, it's a stress subscription.

Mistake 10: Ignoring price history at purchase

A price of 25 USD seems great. You check our comparator: 30-day average is 16 USD, minimum is 12. The game is artificially propped up right now, probably ahead of upcoming DLC. In two weeks it'll drop back down.

Rule: always check price history before buying. Five seconds of work, sometimes 10 USD of savings.

What to do when you commit one of these mistakes

Three paths depending on the scale of the problem.

Loss up to 10 USD. Leave it. The time and stress of refund are worth more. Take the lesson for next time, don't burn another weekend.

Loss 10 to 30 USD. Refund ticket in the store, document everything (screenshots of the Steam error code, screenshots of conversations with the seller, proof of purchase). If the store refuses within 7 days, bank chargeback. Most cases resolve with a refund in 14 to 30 days.

Loss above 30 USD or Steam account ban. Time for more serious action. Refund through your bank card, in parallel a complaint to your local consumer protection authority if the store is registered in your jurisdiction. For a Steam account ban: contact Valve Support, but chances are low here. Prevention beats cure.

What's next

Every one of these mistakes has a common denominator: lack of full information at the moment of purchase. Fighting that is our mission as a comparator. Every price alert, every price history, every seller verification is one fewer chance for these ten mistakes.

This doesn't mean you'll avoid all mistakes forever. I still sometimes click too fast and end up with something I didn't want. But these ten are repeatable enough that avoiding them improves your financial outcome by an estimated 40 percent per year. Calculated across 200 transactions from our users in the first half of 2025.

Three bonus lessons you won't read elsewhere

More specific cases not in typical guides, pulled from my own experience.

Don't buy a key if the seller has more than one active public refund dispute. Marketplace pages show the number of open disputes against a seller. One or two is normal. Five and up means that seller currently has supply problems. Hitting them means a high chance your order also gets stuck.

Check the seller's last activity date. If someone hasn't sold anything for the past 6 months and now suddenly lists 20 keys for popular games, that's a red flag. This is often an account someone wants to dump stolen keys through before getting banned.

Don't ignore reviews from the last three weeks. A seller can have 99 percent positive over a year, but the last 20 ratings can be negative. Sort reviews "Newest first" and read the most recent 10-15 before clicking buy.
