Giftcards.com Misleading discounts Pittsburgh PA

GiftCards.Com sells discounted gift cards from mant different companies. There are currently 6 or more companies selling much the same products on the internet.GiftCards is the only company that I can locate that rounds up the discount on their gift cards. For instance, the company posts a 4% discount on gift cards but actually only discounts the gift cards by 3.9%. The discounts vary based on each company's gift cards that are sold on this web site. In my experience GiftCards.com is the only company selling discounted gift cards on the internet that employs this unethical practice.
