Bought blower from Home Depot but doesn’t appear to be new

I bought what looked like a sealed snow blower and used a discount coupon. I got home later today and opened it and it doesn’t appear to be new. It’s well packed but missing some stickers on the machine, missing hex key, literature had words written on the front page and some nicks on the body. I tested it and it is working. I have a storm coming tomorrow and so I’ll probably need to use it.

What should I do? Should I return it after the storm? Will they give me back my coupon? Should I ask for money back? First time this has happened to me.
