Military MRE's, which I suppose are "real MREs" (four lies instead of three?) are not legal for resale. APack MRE's are made by AmeriQual, who is the largest provider of military MREs to the U.S. military. Sopakco and Wornick Company also make civil and military MREs, which I suppose are "real MREs".

Out of stock at the moment, but $69.95 plus shipping. I've seen them elsewhere for $75-90, some with or without free shipping. Mind you, new production.

The only MRE's that are "illegal" to resale are those stamped US Government Property and were made for and purchased by the USG. The same manufacturer(s) however, produce batches of the exact same product for non-Governmental buyers. Those are the "real" MRE's of which I'm speaking.
Also the link you provided is yet another one of those imitation MRE's. Only 6 different entree items and they studiously avoid stating what the "side items" are. Those side items are crackers, peanut butter, a cookie, electrolyte beverage powder and dairy shake powder by the way. It has a decent calorie content at about 1200 per meal, but rather bland variation with only 6 distinct entrees and the same side items each time. Also makes me question its nutritional balance because of that.
For reference, here's the menu list from the couple cases of MRE's I have stashed (I have one case each of Menus A and B currently, manufactured in 2010), and here's a PDF with a breakdown of some of the MRE look-a-likes.
