Tut tut, Coles Rundle Mall had normal prices for Dr. Oetker at around 6:30 on Tuesday rather than the advertised 50% off price.
Previously I "caught" the same store selling Telstra $30 Pre-paid Starter Kits for full price on Wednesday when they were meant to be 50%. They went through the catalogue and sold it to me for the advertised 50% off price.
But still, not acceptable if you're going to advertise prices in certain periods right.
Did it scan through as full price? Some stores remove/put up specials the night before the (new) sale begins for the next day.
