How much do you like throwing your money away?.
Do NOT use this business. You'll find yourself paying SEVEN dollars for a non-color scan, and what will you get for those seven hard-earned dollars? A piece of feces that looks as though it's been scanned by a copier from 1970. Shades of grey? Who needs 'em? Let's just make an ugly and unusable black and white only scan. Maybe it would make better toilet paper printed out than something you'd actually want to look at. You'll also be paying $10, TEN DOLLARS(!) for a CD with the scanned images. These guys are nothing but a racket. Avoid at all costs.
