Adding extra 'add to cart' options for certain products
I have an add to cart page set up and working well:
what I want to do now is add a couple more Purchase buttons that will work for example:
1: with insurance £25 extra
2. another similar option
Also - these other options are for a certain type of product only, based on the product's categoryID for example
Can you point me in the right direction please ?
thanks for your help
