Any idea how to combine ebates with Bing cashback?

I occasionally see posts from people mentioning double-dipping with ebates and Bing cashback, but I don't see how. Tips? Thanks!

Edit: never mind, I was able to make it work when using Safari instead of Firefox. For later readers, I used Bing first, then signed in to Ebates and searched on the item I wanted to buy.

I can do it in combination with E bay, but haven't figured out how to link the 2 with anywhere else.

Thanks guys-just did it with ebay (using Safari) as every little bit helps. Ebates takes forever to show up though IME.
