I've used BTCLot and have a great services with him.
At first I have tried to order on amazon.fr in every manners possible but it didn't worked. I have talked with Coinbuck during the whole 3 days, he was very responsive and clear. We have exchanged 13 messages in 4 days and in average he answered within the 1.74 hours! That is really quick.
Finally I have given up amazon.fr which doesn't work with virtual cards and instead I have ordered on amazon.co.uk which has worked fine! I have ordered for about 45€ and one of the packet is already dispatched.
Thank you Coinbuck for you excellent service and support!
