Of all the guitars and basses I've bought at Guitar Center and other places, it was always the "floor model" I bought. That seems pretty normal. I don't think "floor model" is the right term. You're trying out the exact ones you're buying off the floor.
I've definitely bought floor models before, and for the guitar it was fine. I was worried about what abuse the floor model amp may have been through, though, and neither item would come with all of the extra stuff (manuals, tools, etc). The 5% off felt like an insult after the BS I went through, and I didn't want to stand around waiting while they wrestled with the system to apply it, either.
