just because Itunes card for $25 will get you $25 in purchases from there sight lets not assume there is not a fee , that fee is just invisable :) remember Itunes sets the prices where they are and they are not selling at break even price the good bet says in the end they make more then $5 on your $25 gift card..
also google is the same way think the $5 fee you pay for the visa gift card is a kick in the but how about the Invisbale fee google gets there is no doubt in my mind when these guys sell music tracks they are making a 4X or 5X mark up on each they no doubt get a kick back from the gift card companies for accept:)
ing them because a good many place will not any longer, to use a vcisa gift card at a store or gas station it must be new and they hold the full value of the card untill what you charged clears the card that can take up to 60days depending ..
so many people have tried to play the rip off game with these prepaid Credit cards no one wants to deal with them any longer ..
keep in mind on average they are selling music tracks at a $1 each and most likely pay no more the .04 cents to do it . this is where the new cloud set up where you pay to just stream the tracks to your self no down loaded copy you cant share it endlessly with everyone ..
