I have been purchasing OEP Stand and Stuff taco shells, meal kits, and taco boats for years. I have noticed in the past couple of years that regardless of whether I used long before the best by date or not, the shells are stale. I thought it may be because I had warmed in microwave, but even when I did them in the oven or cold from the package they sucked. It is too bad, but I think I will be changing my brand. User's recommendation: choose another brand.
