So I come out of Jo's with my purchase of two new Spellbinder dies and show them to DH who was waiting for me in the car. He tells me "You've already got that one". I said "No, I don't". When I get home and hand them on my magnetic wall, I find that I did already have that one. Today I exchanged it for one I didn't have (and bought another, shuuuu"
He does pay attention to what I have, maybe more than I do.
