Sonic started advertising their peanut butter craze hitting their stores. I love peanut butter. I never thought I would love adding it to a burger but I gave it a try a couple of times before this at different gourmet burger places.
There has been one shortage that I have been following for about a year. Really, it seems longer than that. Every time I go to the grocery store I check out to see if this could possibly be the time that the shelves are stocked again.
