Through purse.io, you can buy stuff from amazon, and you even get a discount. I believe you can buy electronics at newegg using btcoin.
awwwwwwwwwwww this sounds so awesome but purse is apparently only for american citizens and newegg doesnt ship to my country. Forgot to say im in Korea
No Purse.io is not only for US citizen. I used it many times and i really like the site. I don't think there is any restriction regarding the countries not accepted there. The site is easy to use, and good point you can get a nice discount for your amazon items :p
I sold and bought both and never had a problem with this site. They had a good idea to create a platform like this. There are others sites as well, just don't remember the name, but they can surely be found in google. Another site you can take a look is Paxfull, i have never used it but you can buy and sell bitcoin similar to localbictoin
