If you want to be carding with a good cc always buy the cc as soon as your cc shop updates and always use a background checker when buying
Some shops mix generated cc with spammed cc.
So if you don’t you use a background checker you might end up buying a generated cc.
Finally I advised you buy from fresh update because a lot of the cc shops get their cc from spammers and the spammers can sell the same cc to more than one shops.
Example is feshop and unicc they get their cc from same source so they mostly have the same cc selling.
A cc that has been bought and used from unicc,can still be on sale at feshop vice versa.
