This helps customers find what they are looking fast and it helps avoid spelling mistakes. 22) Virtual departments – This is a forwarding function that allows merchants to create a category name for during a seasonal period and it forwards visitors to the existing section of the website.

(This should be besides the department page that opens when the top level is clicked.) 24) Filter–based navigation – (As mentioned in #17 there should be a possibility for custom fields. This will allow having a filter based navigation.) Instead of having to scroll through many categories and departments, the visitor can select through multiple checkboxes which products should be displayed. Such as by color, brand, style, features etc. This allows customers to find what they need fast 25) Multiple recipients – When sending gifts, the customer can purchase many gifts and then with one order select multiple addresses, selecting which product/s should be shipped to what address. 26) Mass product updater- One ore multiple products should be able to be exported to an excel file where products can be modified with prices or other information and then re-uploaded to the website. 27) Local pick-up – This is great for stores which want to allow customers to stop by and pick up their order. The customer can choose to receive a text message to their cell phone when the order is ready for pickup.)
