Meijer is currently selling 2lbs tubs of 100% whey protein from Bodylogix for $12.99. If you buy three, that comes out to about $39 for 6lbs.
This is a fantastic deal.
The best price/performance whey protein you can find on an everyday basis is EAS 100% whey from Costco, which is $35 for 5lbs. EAS products taste great, and $35 for 5lbs is a pretty good price.
But this Bodylogix stuff tastes incredible (strawberry banana, sweetened with Stevia!) and the nutrition facts are comparable. It won't mess you up if you're lactose intolerant, it's low carb (2g per 24g of protein), and it's CHEAP.
The deal ends at the end of the month.
