Jenny they do indeed do negative scanning, but it's a separate option.
Here ya go
Personally I was thinking of doing the flat rate box (shipping included in the $99.95 price) and going in on it with my mom. You can put over 1600 pictures in the box (Janet did like 2200), but they have to be standard sizes (no strange shapes, just squares or rectanles). But you can put anything between 3x4 to 8x12 in the box to be scanned.
