Where do you buy your protein shake needs?

The grocery store I work at has pretty limited protein powders.  Is there a website you like that has them for a relatively good price?  My parents have a Costco membership, but I don't want to buy bul****il I try some smaller versions out first.

Don't tell me to go to Walmart either. As the daughter of a union-man, it is my duty to never shop there.

I would like to know this also,  I do get some flavors from BMI surgery  its local for me Its where I had my surgery.  I know you can order from them online though.  I also like Allmax  its Isonatural I think.  Its zero soy and sugar.  I like the non flavored.  My son like chocolate chip but I dont.  I get it from Capitol nutrition,  Again its local so I pick it up.  I have not found much online without soy in it.

Costco.  Premiere Protein RTD shakes.  I love them.  Everyone has different tastes but these tend to get a really good review from most folks.

Amazon.com, unjury.com, Mybariatricpantry.com.  I also get mine at Viamin plus thats in our drug emporium. There are tons of websites.

 I just got syntrax mint cookie (amazon) and am in love. I had to stop myself from making another shake after finishing it, it was so good.  Just ordered an ice cream maker so I can have mint cookie high protein ice cream and be in weight loss heaven. I also drink RTD chocolate from amazon which are okay (better protein, 35 g, for the calories 160). I just ordered the syntrax double stuffed cookie which I hope will be ice cream worthy too.  I may have to get chocolate truffle but still have 2 chocolate protein containers to finish. 
Cheers!

 Check out Vitamin shoppe.com  All I use is Syntrax and they have been the cheapest by far and free shipping!

 Thanks, Michael! I will definitely check it out. 

bodybuilding.com. I order everything from there. I just ordered the RTD-51 (51 GRAMS OF PROTEIN AND 2 GRAMS OF SUGAR), Oh Yeah! RTD and pure Protein. Last night, I used the ice cream maker and made ice cream with the Oh Yeah! RTD and it was great. Also, www.theworldaccordingtoeggface.com is by far the best website with recipes and blogs about weight loss surgery. TONS of shake, smoothie recipes along with great food ideas.

i second the costco premier. maybe you can find a friend wls patient to share boxes with, but nearly everyone likes these. also, go to a GNC, health food store or other such place and buy a single serving package of a variety of drinks and try them. be careful not to get the body builder stuff that has extra carbs and calories.  we live in a rural area and my husband orders most of his stuff from Chike.   diane
