B.S.
try the library. your actual library system may not have it but they should be linked in with the national library system so you can search on and request material from other libraries. I have done this and it works well but it sometimes takes a bit longer to get the books/dvds etc that you want.
like the other mama who posted, I have purchased things from amazon. basically there is amazon and amazon marketplace. the marketplace is the section where you can buy new or used from individual sellers - kind of like "buy it now" on e-bay.
good luck.
