what do i need im a newb just wondering. have subscibed will be otofied of any posts.

You need a table with product id , product name , description, price , coupon/discount ,etc .

what would the coupon discont column be for?

So you can keep track of product discounts.

Just sit down and think what you need to know about your store. You need to know the product name, a description (maybe short and long), a price, quantity in stock, attributes. If you sell nothing but t-shirts, the attributes will be fairly simple. If you have a large variety of different products, you'll need a more complex system of storing product attributes, likely creating a few more tables.

im going to eb selling a variety. are attrubutes like inventorys?
