Hello! Im traveling in north america and Ive already purchased a Surface in Canada. Sadly I had to return it twice in 2 different stores due to pixel and light issues. (pretty bad luck) Now Im on my way to the US and im thinking: Where should I buy it? Should I give it a shot in the US? Im kind of sick of trying it in Canada. Is it safe and simple to return/exchange inthe US as it is in Canada? Would you favor one place over the other or it's all the same? Thanks!
