I'm going to buy a new PC and I'dont know where to buy.
If I buy in my country it is 20% more expensive .
Do you have any good shops that ship worldwide?
I was planning to buy at Newegg but they only ship to US
Any good shops to reccomend?
Need more information.
Hello there and welcome to the forums!
Since this is located in Build a PC, I'll give you the "talk".
I would strongly reccomend building your PC over buying one "pre-built". This is due to the fact that you can guarantee it will be 30 - 50% cheaper than buying it directly from a shop, as well as a lot easier to fix. It's a common misconception that this is super complicated, but I can guarantee it is not. To take someone else's analogy, "It's like really expensive lego". This is a great site in order to build it online:

On the other hand, here is a great video explaining how to put all the parts together:

Finally, here is a build I have made for you if your budget is £1000:

Let me know the budget and I'll make a build for it.
