Query: Buyer Beware!

Received item on time, however, a week into the program discovered numerous empty patch packages and it seems that some of the patches have no ingredient content. Could these be seconds or knockoffs? Not sure, but they're ineffective at curbing nicotine craving and of course, many of the patch packs have no patches in them. Buyer beware, might be one product you want to purchase at the neighborhood store.
