Auto Buying

Hi, I need a script / bot that you buy automatically from Amazon europe (.it / .es / .fr / .de) (with a business account) I would like that once the ASINs have been entered, the process is automatic and takes into account certain factors such as: 1) Buy only if amazon sells and ships 2) Buy up to X quantity of products or up to a total 3) Proceed automatically to the whole operation.
