Is it possible to do a 'buy one - get something free' or even 'buy one - get something at a discount' offer on a whole department?
Eg. If a customer buys a pack of CD's or DVD's i want to offer them a pack of CD markers for half price.
If that isn't possible, can I add a message to all items in a department reminding the staff to offer the deal when items go through the till?
Thanks.
