How does Amazon manage to have multiple new copies of this old book for only $10?
The answer to that is quite simple really, it's just old overstock that's been sitting in their warehouse this whole time. Once it's gone, that's it.
As for the price, as far as books go, unless it's a good to mint condition first edition of a popular story, prices typically end up going down or staying close to original retail over time. Even for collectors or limited editions.

I found a new copy of that book along with a Gameboy Advance stashed in the back of a closet in my parents house a few years ago. Apparently my Mom had bought it for a Christmas present and forgot where she'd hidden it =p The GBA ended up giving the GBA to my nephew a while ago, but I still have the book somewhere around here and I am sure it's still in good condition. I owned the original handbook (red border with a Pikachu in the center) that I bought from a school book fair in the sixth grade.
