Medtipster.com's site is meant to help you locate the closest pharmacy to receive your prescription for $4.00. As with most "advertised deals," there's a catch... each pharmacy has a specific list of medications they sell for $4.00, but those lists are not exposed to the public. Medtipster.com just helps you find your prescription for $4.00 faster :)
Sounds interesting, no, I have not heard of it, thanks for sharing the info.
