A completed signup is not the same as an order. First establish access to the account you intend to keep, then return to the product shortlist. This avoids trying to solve an account problem while also deciding whether a purchase went through.
Use your own accessible email and a password that is not shared with a shopping group. If several verification messages arrive, match the message to the current request. Do not paste verification codes into chat discussions or support screenshots.
Before placing the first order, review the selected size, colour and quantity again. A link opened before signup may return with default options. If you already have an account containing purchases, recover that account rather than creating another one solely to bypass a login error.

Why did my saved product show a different option after signup?
