Yes they do.
No need pad for extra member card
Am not sure if they sell discount cards other than amazon, iTunes and Google play discounted gift cards, something like $92 for a $100 pack of cards. You'll need to join to shop, a years membership is about $70 or $100 for an executive club membership, they will print your card there and then and you can add a family or friend onto that for about $30 for an extra card at the same time.
