Buy 1 at the regular price and get a second one at
I’m getting better at spotting this but invariably I see the “50% off” part and don’t notice the fine print right away. An equivalent way of saying this is that you’re getting 25% off but you have to buy two items. This doesn’t sounds as good, though.
The few times that I didn’t figure out that I wasn’t really getting 50% off before attempting to pay, I was left with a bad feeling about the whole transaction. Do businesses really get much benefit from this trickery if it leaves customers annoyed and feeling a little foolish?
