This allows you to sell products depending on your width and height which will recalculate the price in the shop.
So for example
if the product costs £10
And you have a Width of 9 Units
And a Height of 8 Units
That means the product will be 72 units in size.
Multiplied by £10 = £720
The product can be added as a decimial piont, so could be right down as far as £0.000001 per unit. This allows you to make very accurate small sizes for somethign as large as Garden Gates, Fences, wall paper, paint, carpet, floor coverings, tiles, etc.
The system also has a minimum value, so if the user bought 1x1 of a product they wont pay 1p or something. This allows you to set a minimum of a what ever value you wish.
It also has a Javascript live calculator which updates automatically as you type in the product cost.
I will be adding more info here later on :)
