I get mine from sams club Egg beaters four containers for $8.00.
Each container has 7 servings. So about 42grams of protein per container. It's about $2.00 for 42grams of protein.
I'm going to just buy large quantities of eggs from Sam's club. They're about $1.80 for a 18 pack of eggs. Each egg is about 3.5g protein without the yolk, so it'll be about 12 eggs for 42g of protein, which works out to about $1.20/42g protein vs the $2.00/42g protein from egg beaters. $.80 isn't much, but it sure does add up if you eat this like a monster.
