I want a website which allows me to sell a multitude of products. Each product has a category and I want the website to automatically group by category. Each product can be sold as individual items or bulk, in which case there is a discount. I want the website to allow the end user to choose the quantity and have the website automatically adjust pricing based upon ranges I set. Each product may have a couple variations. For instance, concentration of a liquid. I want different concentrations to be clustered together on a single product page. The website should be able to accommodate different pricing for different concentrations at different pricing tiers for individual and bulk purchases. I would like to be able to upload 5 pictures per product. I would like them displayed as a single image slideshow which can be clicked through like one might see on Amazon. I would like to be able to add a description to the product page. I want a simple admin page where I can ade and delete pages. I want a database backend where the website pulls from that keeps track of items in inventory. Marks them as out of stock if inventory is zero, sends me an alert at a level of my choosing. I would also like an admin page which allows me to modify quantities, pricing, etc without having to get into the database. I would like the user to be able to add products to a shopping cart, calculate a final shipping price, but I do NOT need a payment system. Instead I want to website to generate an invoice and email me (customer info, item ordered, etc), after which I will correspond with them directly.
