I tried to buy a gift card and now it asks me to provide an address which I am not willing to do. Like to know why Swagbucks is asking for address since it is an electronic gift card they won't be sending it to my address and they have clearly mentioned that it will be sent to "my gift card" section. If any one had requested the gift card please do say what is the use of giving an address.
