I recently saw an advert for up to 25% worth of savings, if you buy a package of products (eg multiple products as part of a package). However after clicking through to the deal, I saw that they were advertising it as ' up to 15% off, plus a free product' . So if you included that free product in the price, you would get up to that 25% off in total. But you can't get up to that amount of saving if the value of the free product isn't factored in. It just didn't seem a very clear way to advertise a discount like that. I would rather they just say 15% off plus a free product, not say that you will get 25% worth of savings. Many people like me, wouldn't want the free product, and would rather just have the 25% off the package of products I want to buy. What do others think about that way of advertising?
