There are a ton of free samples available right now through FreeFly's, a site devoted to collecting free sample and coupon offers. You have to register on FreeFly's for access to these freebies, which means sharing your name, address, e-mail, phone number, gender, birthday, and status (single, married, etc.). That's an awful lot for free samples, so make sure you feel comfortable signing up. You also have to turn down (or accept) about 30 other offers to join various e-mail lists to get to the free sample form, which may be more of a pain than it's worth. You decide.
Without further ado, here are the current free offers.
