I have seen the Sunday offers and not been tempted, for that very reason. Anything I might want was cheaper elsewhere.

But with this coupon code, I bought something that had been on my watch list for a long time, as the discount was enough to make it a reasonable price. Saved about 25$. Something that I had not seen in a local store, but was just a bit too expensive to buy at the original price.

So for that seller, it worked for them.

am*3, I bought two items in the one transaction from one seller, but each was over 50$, so that does not quite answer it, either.

but it is OK to buy multiple items and get a discount overall on the transaction. On the single invoice.

for a previous offer, it had said the same thing. Transaction discount, but then applied to only one item. Which was poor.
