Saturday, I was at Sams Club and found the boneless pork tendorloins for $1.89/lb. They are just plain, not marinaded.
I picked up a 9 lb one for $12.xx. I cut it into smalller pieces, vacuumed sealed it, and froze it.
For a price comparison, Cub has the marinaded tenderloins for $6.99. I think they are 24 oz? Not a very good comparsion since I am not 100% sure on their price! But, I do know that the Sam's price is the cheapest I have seen it in a long time.
