What is the best reward to redeem on Bing rewards for someone in Europe?

Hey guys, i live in Europe but i have over 600 points on Bing rewards, im thinking of getting the 5$ amazon gc but i think it automatically applies to your account and you cant trade it on GCX. Anyone have a reward to recommend? Thanks.
