I use Doctors Best Weightloss, and their FB page has a code for 15% off everything! Protidiet, Nutriwise (same as health smart) Proti snax (same as Proti Thin)
I'm in maintainance but I still use some products (mostly sweets/snack cravings) so I stocked up, and tried some new items.
The code is only good Thurs (sorry I'm late posting) and Friday. They always do free shipping on orders over $55 too.

Sounds like I work for them but I don't, just passing on a really good deal.
