Various replies to this thread have mentioned a merchant "contract" which as far as I can tell does not exist.

The only agreement for merchants is the one on the upload form and that's it. Please go read it.

Here's the main part:

"By uploading a product using the form below, you are representing that you are the sole owner of the intellectual property being uploaded or that you have the legal right to sell the intellectual property on behalf of the owner. You agree to indemnify Bondware Inc. in any dispute which may arise regarding products that you sell through this site."
