360 replacement query

[Shamikebab]

My friend's 360 has 3RROD she has had it less than a year and I said she could get a replacement from the store she bought it from. Is there anything we need to bring other than the console and receipt? Can they test it and find out it's working (it doesn't red ring every time yet) then just make us go away?

Thanks in advance.
