Hi everyone, I am rather a newb so please any help will be appreciated.
I am trying to add a custom page to the cart that can perform as follows:

Basically I want to add a link to the Categories section that says
"products from $15 to $25"
This link would take the user to a page that will out put all the products that fit that criteria (or any other customized criteria).

My store will be selling wine, so another example would be a link that said
"Wines from California"
This link would lead to a page that only listed products that originated from california dynamically.

Could someone please guide me on how to make a custom page that can produce this sort of dynamic content?
Thsnks!
