I've got a resource, say a web-page. The page represents a product that belongs to one of the categories. For instance, Toys(category) -> Robocop (product). There's a link on the page that takes user to another page with suggestions on places where the toy can be bought. Is it going to be grammatically wrong to entitle this link "Where to buy" or it's fine to appeal to ellipsis in such situations ? Thank you.
