keep in mind too staples probably has some really good scanners. Scanners are like digital cameras and although they will work, some work better than others. So likewise if you went out to buy your own scanner it might not have the same quality. So maybe you are paying for a combination of NOT having to buy a scanner, NOT having to scan it yourself, AND getting slightly higher quality.

Who knows, i'm sure there was a starbucks around anyways for your convenience.
