Seems like they had a problem with that for a few batches, we also had little moths or something in a couple of bags. But that was—boy, I can’t even remember, maybe 2-3 years ago, and I’ve never had that problem since.
At any rate, if anyone DOES use it and wants the coupons, I still have them. Those big bags are just too much for me to handle, and hubby is in a foot cast for several more weeks so he can’t carry them, either, so we won’t be able to use the coupons before the end of the year.
