However, if you are prepared to accept Steem, then there is a decent steem marketplace that accepts both steem and steemdollars:
https://www.peerhub.com/
There are even second hand cars listed on there, as well as lots of crafts and stuff.
Why not, do you check the digital goods section or not bro. There are various website apart from this bitcointalk forum to buy the products with the bitcoin. I mostly suggest the purse.io website to buy the products on ecommerce website bro.
In this website you will be able to get the rewards such as points to get products with additional percentage offer. Then you can access the Amazon.com via this website bro. That is actual option I tried to say.
