On special - but you pay the full price

The Superspar at the Paddocks was offering a special on their Milk Tarts - was R29.99 now priced at R19.99 but when you get to the till and pay for everything, you actually end up paying the full price.

Amazing how many shops do this, advertise a special and when you get home and check the till slip, you realise that you have actually paid the full price.
