The card from Sam's (or the MCI card from Costco that I have) are about 3 cents a minute for domestic. If you look at the cards at Walmart, or any other retail outlet, the domestic minutes are going to be higher. A card for 500 domestic minutes on the Walmart web site works out to 6 cents a domestic minute, so twice the price of the Costco or Sam's phone card.
