Little Verbena, I got my protein powder samples online. I wanted to post links but can't because I haven't reached 15 posts here yet. Anyway, try Googling:
"Unjury starter kit"
"BJ's Bariatrics Syntrax Sample Pack"
"Nashua Nutrition Protein Powder Samples"
"Vitalady Protein Samples"
and you should get some good results.
