Use A Department as Cross Sell

Where a range of products are all likely to have the same Cross Sell then use a Department. e.g. if you are selling TVs with out aerials then you could use the Aerial department as Cross Sell on everyone.

You would need to be able to add other products as Cross Sell as well.

DO NOT add the complexity of excluding one or two items from the cross sell department on a case by case basis.
