this thread will be very useful for some people, hope for the OP to fix what they have made. because this thread is a reference for some people, it's even better to add some of the ones that have been suggested. to be complete
It's already fixed, working on adding the sites listed by members.
This list could be much bigger than it is now,given the increasing number of retailers which are beginning to accept BTC as a means of payment.I'll write some of them now,but with time I will probably also remember some others.
I'll do my best to keep the list updated and follow the news, I was planning to make a list as personal reference, but then thought of sharing it with the community.
Thank you for sharing these good sites. It's a great topic and very informative, I hope that you can add more and make some updates every period. I know a few of these sites, and I enjoyed seeing in which way can I use my bitcoin for the sites that I don't know. Keep updating this topic, and I am sure that you can be awarded by a lot of merit points as the idea is very good.
Glad to hear that you liked the list.
