Unfortunately I found out not all stores carry all the grades of the different products. My local store for example, [1 mile away] only carries Edge in 5W20 and 10W30. The store 5 miles away carries it in 0W20, 5W20, 5W30 and 10W30.
I think they use different stores to test market products, at least that is what one of the managers told me. I still find it odd that one store only carried 2 grades of Edge, and another AAP doesn't carry MMO, which I find extremely odd.
