Hey everyone, I'm looking for a nice customer AND admin friendly cart for my store. Currently I'm using BuyItSellIt and its ok I prefer it to all the others I've tried but I just know there has to be a better cart out there. One that allows discount codes, Shipping by Weight, shipping variances by product, product customization options such as choosing a color or size. I'm not sure what all I need to point out. I don't want to use Zen Cart or Mals... Anyone other options? needs to be very affordable
