I gave bought a good bit of stuff on Furbuy, a corgi partial, tons of fur, hand paws, too many tails, a collar, and so much more. It is all about the people selling the stuff. I personally won't put a bid on anything if the seller doesn't have a postive feedback.

So when te runs out that's when u buy it will something pop up saying u won and then something will pop up to show how u would like to pay causr idk what happens

When the auction ends, you get an email from furbuy saying you won ( if you won) and most of the time ( for me at lest) the seller also emails you to exchange information and total cost to be sent. Then you pay then that amount and they mail your item. Then both parties can leave a feedback report(review).
You can add items to a "tracking " list where you can keep an eye on auctions without bidding.
I think it is a pretty cool site. Tho there has been only one time where the person took like 4 months to mail a pair of handpaws... but she kept good communication and was understandable.
