Always remove the top of a jar to make sure the inner seal is intact
We bought a jar of PB at Walmart and when we opened it a few days later, found that the seal had been broken and 2 finger tracks were left on the surface. We returned it yesterday with no problem.
That's so nasty. The brands of PB (and almond butter) I buy don't have an inner seal. They're glass jars with that shrink-wrapped plastic seal around the outside of the lid so it's easy to tell when it's been broken.
I had to return a vitamin supplement to CVS last night because I didn't realize when I grabbed it off the shelf that it was missing the outer AND inner seals. No finger tracks, but who knows what some lunatic could have done to the contents.
