Is there a script that i can use to search and buy things in a store while im not there? Like could i program it to search for like shoes and write in a certain price to pay for them and the script would buy them for me while im gone?

You can use something like WWW::Mechanize (http://search.cpan.org/~petdance/WWW-Mechanize-0.65/lib/WWW/Mechanize.pm) and a cron job (or a few) to do this but it's not a trivial task. Something like this would be specific to a given storefront and possibly even a given item at the store.
