@Tai Chi,
It did show the coupons used.
I'd bought a dozen items, and used 4 or 5 coupons.
I had to think for a second if I'd used a coupon on that particular item.
I also remember I had a coupon for something, but when I actually saw it, didn't want it.
I don't remember what that something was.
The number of coupons and inventory have to justify?
Well, that would be a problem if every person that came in the store used a coupon for a particular item.
Then they would have to prove they actually sold 800 boxes of kleenex, if they were holding 800 coupons.
In reality though, there inventory of kleenex was down by 800 boxes, and they were holding 42 coupons. So they would have to justify to someone that if they held 42 coupons, that meant they must have sold 816 boxes of kleenex?
The number of items sold is so large, and the relative number of coupons for any particular item is so small, I don't believe justification is an issue.
I would expect them to reimburse me for the amount of dollars they are going to gain. They are holding a piece of paper that is worth $3 to them.
The cost of returned items is already built into their budgets. They know that for every X amount of items sold, Y% is going to be returned, and they have already accounted for that.
In essence, Walgreens, based on the knowledge of millions of items sold, and the thousands of returns that are made, we fully expecting me to return that item.
It was just in the odds that me, or the person 3 people behind me in line, was going to have to return something. They also have a very clear idea how much is going to be damaged, stolen, expired, etc.
If they store keeps the $3 coupon on an $18 item, returning only $15, they made an extra 16%.
