Completely free

Create as many auctions as you want at absolutely no cost. Combine auctions into a gallery to advertise multiple items at once.

Easy to create

Creating a new auction only takes a minute and can be updated at any time. Advertise your auction and you're done!

Use anywhere

BidKat improves the places you share your item - craigslist, Facebook, Twitter, classifieds, or a bulletin board. It's not a replacement.

Auto negotiate

Not great at negotiating prices? BidKat will do it for you and get the best price possible while being fair to buyers.

Maximize profits

Buyers always make the first offer so that you're not leaving money on the table if you are not sure what your item is worth.

Increased privacy

BidKat will collect offers and questions from potential buyers without ever revealing your email address.
