Bitrefill - recharge your phone credit balance using bitcoins

Hey I came across this useful site called bitrefill. It basically let's you refill your phone credit amount using bitcoins. I was skeptical at the beginning, but as I went through it, and did the necessary steps which take only 5 minutes. (Sending the bitcoin amount to their address), I received the credit refill on my phone. I was shocked.

Instead of going to the boring market outside to buy a card and refill your phone credit, you could do it through the internet instead nowadays, with the help of some Bitcoins.

So I thought, the bitcoins are a wonderful thing, but sadly they are not accepted in popular amazing sites such as Amazon, e-bay, Ali-Express.. So guys, what about you? Do you know any wonderful sites that provides you service using bitcoins? If so, please let me know about it.
