"...Costco Wholesale Corporation, the leading warehouse club operator, to carry MusclePharm's Combat Protein Powder nationwide in all 430 stores beginning late October 2013."
Costco is probably the very best we could hope for. Much better margins than Walmart allows vendors, and stores within reach of everyone in the country.
Here's the best part:
"Combat Protein Powder will also begin rolling out to Costco international locations in the later part of 2014 and early 2015."
If you read MP's facebook page, people from Canada, Australia, Eastern Europe, etc. complain that the websites don't deliver to their locations. This will (eventually) solve that problem, since Costco has a fairly wide retail presence overseas as well.
