AbleCommerce Shopping Cart Software

We have a scenario where a Vendor is willing to offer a discount if 2 specific products are ordered together.

I could obviously take product A and Product B and create a new product listing with the 2 of them together, but my client wants to know if we can offer some sort of promotion that shows the 10% discount on the combined purchase, so a customer could buy product A, add product B to the order, and receive 10% off the total of the 2 (discount wouldn't apply to other items in the order)

Has anyone set anything like this up?

You could do it with a kit of Product B for Product A and take the 10% off both products by taking that $ amount off Product B.That way if the customer removes ProductA from the order, he doesn't remain with a 10% on ProductB. If you use checkbox display for the kit, they don't have to select anything.

Thanks Judy, this gets us most of the way there.

Turns out what the client wants is ALMOST accomplished by this. The problem is they want to optionally have one of a list of items accompanying the product.

A checkbox does this if there is only one item that can be paired for a discount, but if you have more than one product, but they can only pair it with one - you need to use a select list or radio buttons. The problem is, there isn't a "none" option (a real product has to be selected). I thought of creating a fake product called "none" with no cost. The problem is this is an ugly hack and opens up potential problems with shipping, order fulfillment etc.

Yes, that is a problem with the new AC7 kits- you can't have a non-selection in a select box. I've been meaning to look at that for a work-around. The options show up with no selection because Able added:
aspOptions.Items.Add(String.Empty);
I haven't figure out how to do it for kits.
