Well, Apple charges the same 15%; you only have 14 days to return, plus sales tax.![]()
You can talk to them about this. Some are reporting that a hard fast 15% is being applied, others are saying there's a 5% discount so the restocking fee is dropped to 10%. If the bastard genius had it his way today I would have paid him to take it back! Turns out the sales staff and specifically the manager was willing to take it back for a full refund in the form of a store credit. I cannot complaint (and won't dare).
I think the key is patience and never really showing them that you're frustrated. For me, I just continued to e-mail a friend of mine all my rants and annoyances. The truth is I was overtired when I went to the store and I should have waited until tomorrow, but I had it in my mind and just did it. There was little to nothing that could be said that would have talked me out of it. In the end, I feel much better. I haven't fidgeted with my 30" display all night!!
