There is nothing shady about it. I simply was fourth right with the fact that I will be charging the paypal fee back to you. That way to can see what I am charging you for. I could be shady and mark up the price more that the paypal fee and try and take advantage of people as alot of people do on the net, but I am a honest guy trying to sell people something they can use for a fair price. What you are concerned about adds up to 3 cents on a dollar (lol). It is really nothing to worry yourself about. For those who can't add here is an example:
Say you spend $30 with me. I will add 90 cents to your total. If I do as FullSpectrum suggests and add a buck or two each card I will be charging you $60 for a $30 order. Which would you prefer??? Even if FullSpetrum was implying that I add $2 to the total I would still be charging you twice the cost. Any questions.
