I'll keep this post short and sweet:
Check them out, sampleaday is a great sample site, that actually has some unique, but useful items. As well, the author definitely brings humor into the reading... and since I had some time to kill, I had a chuckly and enjoyed his little posts.
Lemontide has been the newly "old standby"... they are a cool site, and while I am not as active with their forum and overall site, I absolutely love their posts... 99% of their items are useful to me. So, I am relatively certain that I can say everyone will find something! :) As well, they have a drawing for gift cards, and again, I am not as active, but I have seen some great prizes, from a Wendys to McDonalds and Starbuck (methinks)
So, check these out!
