A40cr cards

I 'm ready to to buy some A40CR cards. And I have visited several shops to compare the price. The price of A40CR in one online-shop is about $7.50, but in your store is $2.00. Is the card you sell exactly same as the cards other shops sell? Is the function of your card reduced or something else?
