It's fine, as others have said. However, I do not think you are fine with it. It's not the tank you really want and then the trim and tank are off kilter. This will probably eat at you, and you will not fully enjoy it, even if others say they would use it.
Take it back, don't worry about the LFS and if they will be stuck with it. It's your hard money, get what you want and don't settle. This hobby, hell, many hobbies are too expensive to not get something to your liking.
Is there another LFS you can order from? I'd drive 2-3 hours to pick up a tank.
