.Where can I buy wholesale brand name discount cards for resale?

I have owned brick and mortor businesses in the past, and have made a living alone on ebay for a few years. Currently looking for a consistant product ( or products ) to sell on line. Knowing there is a down swing in the economy discounted gift cards comes to mind......
keeping an open mind as to anything small, easy to handle and profitable. I'm sure this is a unique request. Ha, ha.
Thank you for any input.
