I am looking a for way to change the price of a product depending on something that the customer inputs during the order process.
I am working on a shop which sells printed wall papers, mouse pads etc. The customers have the option to either upload their own fotos or choose a picture from fotolia (via their business api). But as each picture from fotolia has it’s own price, the final price of the product depends on whatever picture was selected.
Any tips on how I can achieve that?
