Gift card site Gyft has a $5 USD free gift card offer for new users. You can apply this code against a $15 gift card purchase straight away - making it cost $10 USD.
One of the cards you can buy is Amazon US.
I have tried this personally and it works (using paypal). I have also purchased items with the Amazon credit and they were delivered fine
There is also still 2% cashback for Gyft and the $10 USD Topcashback sign-up bonus (on referral). But this is not necessary to get the deal.
PS: I think this is worth reposting as a lot of people may have missed it last time. The other deal is also marked as expired, whereas this aspect of it is still running.
PPS: I bought another one just then - so this is very recently verified.
My Topcashback referral link.
Pretty cool option to get cashback on amazon gift card purchases.
Has anyone tried buying the ebay gift cards? Maybe would help for US denominated purchases?
