Two options, no "System" — we follow your phone until you touch this, then we remember what you chose.
A price check needs no account — nothing to log into, nothing to delete. If you lock in an order you can sign in with a code we email you, so you can follow it; that's optional and you can ignore it. We keep your question, the verdict we sent, any order you place, and your WhatsApp number if you gave one.
buying questions only — never advice on use
