We prefer not to describe websites in terms of 'numbers of pages' or to set limits on numbers of products you can have on your site. We'll work with you to find the best format for your site to give the user the best most productive experience. If you sell thousands of small items, with lots of variations then we'd give you a grid system for your product listings and make it as easy as possible for your customers to find what they wish to buy. Alternatively if you're a fashion brand and wish to profile collections, giving each item an elegant beautiful presentation we'd divide your site into the appropriate sections giving each item its own page. Either of these options results in very different websites with very different numbers of pages, this is why we don't set limits.
If you have need to add a lot of products or a lot of new pages regularly we will work with you on the best format in which these should be made before you send them to us to keep your costs down, and to keep your package within the standard fee.
