My answer, https://money.stackexchange.com/a/63749/25694, was converted to a comment and I am not sure how to find the exact reason for it.
I received a moderator flag that this was a better comment than answer. When I looked at it, the answer had no more details than others already posted, basically "ask." As Keshlam noted, the Best Buy reference wasn't helpful. Many US stores have this policy, but OP is in the Euro-zone.
Note, right now there are 8 answers posted, and probably only 3-4 are unique.
