Hey if you need some help saving for a kindle, try using the swag bucks search engine. It's powered by google and ask.com, and you get "bucks" for searching. You can use the bucks to get amazon gift certificates. It would take less than a month to earn a $5 gift certificate using the engine every day. It's not much, but it might help:
