Do you know about the Bing.com eBay Discount?
I didn't until a Discount Duo reader posted on the blog about it.
Basically, if you live in the USA and use bing.com to search an item on eBay, a
gold circle will appear with a $ beside it. Each time you search for the item using bing.com, it
could be a different % of cashback you would receive. It fluctuates.

I also wanted to let you know that I've started researching about other
auction sites that are available online and hold a good reputation
among their users. I will have the information available at a later date and
if their are enough requests I will just send them out to
the newsletter.
