is it possible to have PDF files in the cart for purchase downloads

like for instance if a customer buys a product and its a pdf file that is a parts list for a chainsaw or a blower or mower is there a way to fix this to where they can instantly download that pdf after paying for the item ?



reason i say that is i have tons of parts diagrams i am scanning into pdf files and was wondering how that can be accomplished to put in the cart system



i wish also to upgrade to 1.3.5 sp 4 if someone can help me out there

cause my reward pts is not working right i have to manually add points to customers they do not get added automatically
