I agree, I am a price watcher, and not really a Wal-marter - but I have been amazed at their prices on herbs and vitamins. They have a better selection than all of the big pharmacies. I should probably check out their other stuff while I'm there .....
my walmart had saw palmetto and royal jelly and a really good price on omega 369 complex, ginkgo biloba. but they did not have fenugreek, vitex or wild yam at all. good luck!
amazon.com isnt just for books these days... i order a lot of my herbs from there because they have good shipping rates, are pretty fast, and you can compare prices and they are usually cheaper than even walmart...
plus i moved overseas, so now i have fewer choices, but i would do the same if i were in the states...
