Is there a place, where i can buy everything in other countries and pay with bitcoins?
I know there is a place somewhere.
I recently heard of http://bitcoinstore.com
They don't provide "everything", and I'm not sure how shipping works, but they have quite a large selection. The way I understand that it works is they take in bitcoin, convert it to dollars, and then pay the actual provider of the item(NewEgg, Amazon, etc)
One option is to use OKPAY they accept bitcoins to fund your wallet at a "market rate" and then you get credited Cash in your wallet.
They also have the ability to create a virtual master card which i thought is pretty cool, so you can essentially use it online.
Although you do need to be verified to use their services.
Note: At the time of writing this, the market rate was $30 cheaper USD per coin compared to BTC-e (normally one of the lower values) , but depending on how badly you want to spend it everywhere, its not bad.
Right now the it's still hard to buy everything using bitcoin, but you can use bitcoin to buy gift cards from gyft and use it at many places.
