Exchange at Best Buy

[Baffles]

So I have a tiny little scratch on my screen, hardly even noticeable, but my screen protector doesn't want to come clean so I can't get it to go on without looking ****ty. I don't know if I should try to get them to exchange it at BB by complaining about the unsensitive edges/speaker (which really aren't a big issue on my phone, screen is pretty good at the edge and the speaker seems to sound fine) or not.

I may buy some screen protectors on ebay that are labelled as being for the touch pro, but I'm not sure if they will fit or not.

I don't know what to do....
