Need to be able to offer similar items when something is purchased

[random183]

Hi,

 

I'd like to be able to offer similar items which can be bought at the same time as the main item.

 

Take the following for example, we sell handmade clothes and somebody buys a top in a specific colour, it would be great if on the same page I can have a tick box or similar with "Order Matching Shorts" in it which would then automatically add this to the shopping cart when somebody adds the item(s)

 

I've had a really good look around for a contribution that does this (I've been looking for at least 2 weeks off and on!), and can't find anything suitable.

 

Does anyone have any thoughts or can point me to a suitable contribution?

 

Thanks

 

Mat
