Apologies, another technical issue - 

I've set up a multi-buy discount for any item which falls within the Postcard category, but when I view any of my listings within that category, there's nothing to suggest on any of the listings that buyers can benefit from a discount. The multi-buy offer only appears when view your basket. Here's a few item numbers to look at:

127554817610

127540555726

127540117840

Usually, there's a banner which appears at the top of each listing if there's a multi-buy offer available, but not in this instance. The multi-buy offer has been in place for a few weeks.
