"Other" Giveaways

The "Current Giveaways" widget on the top right of each page seems to be a popular thing. I'm trying out something else PromoSimple offers. Basically, I pick different categories, and then they provide a list of giveaways available in those categories from their live feed. For starters, I picked categories of "Toys & Games", "Internet & Electronics", and "Gift cards & Cash". 

If you'd like to see different categories, please let me know. I may decide to rotate them every once in a while. Or, I can always just pick "All categories".

I still prefer Rafflecopter for my giveaways. Does anyone know if they have a similar resource/widget available?
