What is the TRUE cost of these Briefs?

Well, I would like to buy this but this page is very confusing. It lists 11.00 each and then it states SALE price of 7.50 each. Yet, when I place the items in my cart...the sale price does not appear. Very confusing to say the least.Bali is a very good name and I am sure I will be pleased BUT before I purchase..I want to know the TRUE COST!
