Query: Disappointed

I am an avid fan of these pretzels and order often. This particular box had a rancid smell and bad taste to them. I was very disappointed as I purchase these and the whole wheat pretzels often and have never have this problem before. I will hesitate to order again as they can't be returned. This particular product has no expiration date so it is difficult to determine shelf life but like I said I normally would give them 5 stars!!
