In line with many other shopping carts, I would like to see cost variables available for the product options. Many carts simply add the value of an item enclosed in brackets to the item price. Along the lines of option A (+0.50) etc.
Many basic javascript carts and php carts (even free ones) offer this simple functionality and this is a noticeable shortfall in the basic version of Shopping Cart Creator 3.5. Most garment sellers for example, charge an extra premium for XXL sizes etc, to reflect the extra charge levied by their own suppliers. Likewise items that offer a choice of finishes, charge extra where more expensive finishes are specified. The other alternative is to have a separate listing for every option, which is both tedious and confusing for potential buyers and definitely not a good shopping experience.
I just feel that lack of practical functionality, seriously limits the capabilities of what is an outstanding and very user friendly product.
Great product guys, but don't lose focus that some of us don't want the pro version, just want the current one 'tweaking'.
