I have a few of those entres left around here somewhere. Not sure where though:) Those are hit & miss items. They might still show up on occasion.
Actually, I did some further looking and was able to find a pack of 18 Menu B entree-only MREs with a July ‘11 mfg. date on eBay for 49.00. Even with the shipping that’s only $3.36 per MRE. Not too bad. Best I’ve found so far.
