We are trying this ad on the bottom of receipts today to promote OK! and Who which come out tomorrow. It has been set to run only on Thursdays automatically – so we don’t have to remember to include this. Using the receipts like this makes them more valuable than just a record of a sale.
Other coupons we have produced contain offers to reward customers for loyalty if they come back within a certain time of the sale. I think that sometimes retailers complicate loyalty programs and make accessing the prize too time consuming.
