Most people know that you can on the bottom of the receipt put in a discount voucher, or you can give points on a VIP loyalty marketing system but there is much more you can do with it.
Consider using the receipt to send promotional messages too. For example, why not promote a marketing season in the shop. Easter is coming; public interest in Easter is high. Looking at google trends its currently just over half of that Christmas.
If you have something to offer people for Easter why not do so. You have a buyer here, why not try?
Another idea is using your receipt message to promote your Facebook page or website? Here is a person who buys in your shop, why not push the shop online too. Why wait for them to find you on Facebook? All you have to do is put the web address in the receipt message.
Finally, I do believe that it is a good idea to include your shop's contact information on the receipt, they have a receipt why not make it a business card too.
