This stuff is amazing. We found it at Walmart a few months ago, it is comparable in price to mayo/salad dressing and it tastes good. To me it's like mayo married salad dressing (aka Miracle Whip).
Rumor is that Target carries it (our Target is never a good judge, they clearance stuff after 5 minutes so I never find it) and Kroger (again, never found it). I am finding it consistently at various Super Walmarts and Walmart Markets (okay, we have five locally that I can and do frequent).
We just found it at Publix tonight!
I don't even want to discuss how many containers we have inhaled lately. DS1 has NEVER been a fan of Veganaise and he loves this stuff.
