Yep. Office Blank, aka Staples, coupons and discount cards actually used to be worth something - flat $10 off $20 or more purchases, often a flat 33-50% discount, no gimmicks. Now they are more like 10% discounts on very, very limited ranges of office supplies - no “technology,” no ink or toner, not usually furniture or cabinets, nothing but paper, pens, paper clips, folders and the like. I throw them away without looking these days, when I used to prize them like Xmas presents.
My main point was another example where “gold” does not mean the metal. So that calling a gold colored coin a “gold coin” in an ad isn’t false. I suppose that point has already been made several times, but it doesn’t appear to have sunk in.
Yes, that one pisses me off. All they needed to say is something like, “20% off everything you can fit in this bag, from our range of specially-selected items” and I wouldn’t have a problem with it.
Am I the only one wondering how you are supposed to fit chairs and furniture inside a standard-sized cloth grocery bag?
Hmm. I’m thinking about the old tale where the king wants to buy “as much land as will fit within this bull hide.” The deal struck, he then has the hide sliced into razor-thin strips and encircles an area miles around.
“Do you have a definition of ‘in this bag’?” 
Queen, actually. Specifically, Dido of Carthage.
