Not Currys PC World.
A friend bought a laptop for some work. Display failed after about 2 weeks. "Certainly madam, just leave it with us and we will get it back to you in 6 weeks." This was no use since PC was needed. She bought another one and ended up with two. I was present during the attempt to return faulty thing and it really happened this way. I was not intervening though since then everything would have been my fault.
Their solution is that you need to buy an extra warranty if you want to avoid that scenario.
