If it's the same sale they had last year, the "coupons" are literally on the bags. And, if you get a particularly unobservant TSC employee checking you out, you can get buy 1, get 4 free.
And I thought the buy one get one deal last year was good I've still got two bags left from the ... 60? we bought then. Tough to say no to $10/bag grain, and my horses do better on it than they do on TC Senior!
I know, I loved the BOGO, even the Buy Two get one free.....I think those days are over lol. My horses do incredibly well on this feed...I should be stocking up for when they come off grass. I got three bags of Strategy at TSC last weekend only because the bags must have ripped a little, they were still basically full but taped- $10 each. It was physically impossible to walk by without putting them in the cart. They can eat that when they start back up eating grain but not really needing it ;-)
