I don't see anything wrong with grabbing thicker packs since they are obvious and don't require any searching to find.
I'm more concerned that the OP is for some unknown reason mad at Panini because he bought some thick packs and they were decoys. That's the whole idea, did you think you were assured X number of hits if you bought as many thick packs as you could?
