How to judge whether a subscription reseller is trustworthy
Ignore ratings and sales counts. Look at whether the shop states its process, its warranty boundary and what happens when something fails.
In this market, the best talkers are the most common and the ones who deliver are the rarest. Ratings can be bought, sales counts can be faked, screenshots can be staged. What cannot be faked is writing the rules down — because clarity costs a fraudster money: every boundary he states is a handle he hands you.
1. Does it state the warranty boundary
An honest shop separates two things: the subscription dropping inside the paid period is covered, and an account restricted by the vendor for breaking its terms is not — and nothing sold alongside can insure that second case. Writings like "warranty for everything, including a frozen account" cost the seller nothing today, and you will not find him when it matters. One seller willing to print "a ban is not refunded" is worth more than ten pages of five-star reviews.
2. Does it ask for a password
It must not. Activation needs an identifier, not a login: the Claude Organization ID from Settings, then Account, prefixed org_, or for ChatGPT a session token taken from the official page. Anything asking for a password, a 2FA code, a recovery code or a full cookie jar is wrong at the level of the process, not the level of the shop.

3. Is the price implausibly low
The official price is public, and we print the official CNY equivalent next to ours: Claude Pro 105 against 134, Max 5x 523 against 668, Max 20x 1047 against 1336, ChatGPT Plus 95 against 134. A real reseller carries channel cost and risk, so his number sits near the official equivalent. A listing at a third of it is not a discount, it is an explanation that has to be demanded: either an account shared with several buyers, or a payment made with someone else's card. When the second one is reversed, the subscription and the seller both disappear.
4. Is there a reference number
A real flow gives you an order number you can look up and quote to support. Nothing is emailed here — there is no mail system behind the order — so your record is the order number plus the on-chain transaction hash. Without either, your only record is a chat, and a chat can be blocked with one tap.
5. Is the delivery estimate honest
For a step that requires human verification, promising "two minutes" is itself information: either keys are delivered by a machine, or no human intended to be involved. A believable line is "usually fast, worst case X", plus a named place to go when the estimate slips.
6. What the failure page says
Read the refund page, not the homepage. You want a formula: order amount multiplied by unused days divided by total days. You want to see that a replacement subscription is offered before any refund discussion. You want to see that money goes back on-chain to the address you sent from, usually confirmed inside twelve hours. "Refunds supported" with no mechanics attached is not a policy.
7. Ask a boring question before paying
Ask something trivial and watch how long it takes and how it reads. Someone who documented the process does not improvise when the question is dull. This single step filters most of the market. Here support is @cdkstorebot, in English or Chinese, and the public channel is @cdk_store.
The honest bottom line
No seller can make a promise to the vendor on your behalf. Anyone printing that kind of promise is betting you will not have trouble inside a month. Remembering that one sentence avoids most of the traps in this market.
Our own rules are in the refund policy, including the unpleasant one: a ban is not refunded. Why accounts get restricted is covered separately.
Common questions
Do you cover a ban?
No, and no one else honestly can. A subscription dropping inside the paid period is covered; an account restricted by the vendor for violating its terms is not, and it cannot be insured by any third party.
What information do you need to activate?
An identifier, not a credential: the Claude Organization ID (prefix org_) from Settings then Account, or a ChatGPT session token. Never a password, 2FA code or recovery code.
How do I get a receipt if no email is sent?
The order number and the on-chain transaction hash. There is no mail system here, so those two are the complete record, and the hash is publicly verifiable.
What does a refund actually look like?
Order amount times unused days divided by total days, with a replacement offered first. Money returns to the address you sent from, usually confirmed within 12 hours.
A shop quoted me a third of the official price. Is that a bargain?
That is a question to ask out loud, not a discount to enjoy. Either the account is shared or the funding is someone else's card; when it unravels, the plan goes first and the seller goes second.
