MyProtein is having a 30% off site-wide sale right now which does not take a coupon. For an additional 40% off, at checkout use coupon code:
HONEYVIP

This can be used on anything in the site, but I found the 11lb bags to be the most lucrative. That puts it at $5.25/lb for Whey Isolate which beats the previous front page deal with 181 upvotes, which was $5.45/lb for Isolate. Both crush typical amazon/walmart prices of $10/lb though.
Alternatively: If you don’t care so much about the slight calorie difference, and protein % difference, and just want a good deal on protein then there is this:
11lbs Whey Protein – $45.42

Also use code: HONEYVIP
(No I do not work for honey, nor do I care if you ever use them. In fact this is the first time in months that I have actually used it successfully.)
