People will only ever pay what the item is worth to them but if I am on the fence about something I am more lilkely to decide to buy it for 60 than I am 90. There are items this weekend that I decided to not get because they were 90L. Fact is you get 5 people that buy at 60 and now only 3 will pay 90, you're not going to get as much money out of your sales.
