Where to get foam?

[Casey2124]

Hey guys! I have a question, where do you buy your foam at?

I have Sears, Best Step roll (6mm) for $26.99 (46 in. x 93 in.)

Harbor Freight roll (8mm) for $7.99 (Length: 72 in. Width: 24 in.)

Pep Boys, Best Step roll (6mm) for $24.99 (???)

Or what suggestions do you have?

What is better for a foam Iron Man suit, 6mm, 8mm, 12mm?

or I just found:

CAP Antimicrobial EVA foam roll for $20 (7mm) and the same size as Best Step.
