Hi sorry for the delay in reply.
I have to types of products, one is a display & another is items that go on to that display. I would like to offer both items as seperate sales but I would also like to offer my customers the chance to purchase them together as 1 item at a cheaper cost then it would be to purchase them both seperatley?.
For example - If a customer comes to our site & already has product A but wants product B to go with A I want product B available on its own to buy, which I have done already on my site. But if a customer comes onto our site and wants to purchase item A & B together, I want to combined the prices & take off 10%
I hope this makes sense, if it doesn't I'll try again haha.
Thanks for your help
Kerry
