Just have them send you one D2U (Direct to you).
You usually get it in about 3-4 days, and no charge for shipping.
Some stores put their scanners in what they call fish tanks (glass cages) so that customers cannot steal them. If it is in a glass cage, and isn't turned on, most likely it has never been used. However on the other hand it could have been on the display, on 24/7 for a year or more.
