I have a site where a client wishes to sell products that have a lot of different variations (ie size, colour, length etc), but each of these will make a slight change to the price. I know about the ability to make variations of products so that the price changes when you pick different items in the drop downs, but these have to be manually entered. For my client, each time the variations are open to the end user, the price increase will always be the same.
Both have the size option available to user -the price will increase on top of the base price by the same increment based on the selection.
eg: Small = no change Medium = +£5 Large = +£10
Product A, starting price: £10 Product B, starting price: £20
So Product A with medium will be £15, Product B with large would be £30
I realise in this example it would be simple to add this in manually, but if she has 3 (or more) different options open to the end user, with upto 10 options within, multiplied by her entire product range, it would take forever to do.
What I had thought is if it was possible to add a price addition field to the product category listing, and then use a (rule/module?) to automate this price being added on. Is there anything already out there that does anything like this, or if not, how could I go about creating it.
