In Woolies this afternoon doing a batch of shopping. Shelf advertises 2 for $11 on Kirks branded 10 pack soft drinks. Normal price is $8.69. When I took them to the register they showed up as individually reduced to $4.34 but then when the second one was scanned it also took off the value of the two for one offer as well - $6.38. This would have brought the price down to 2 packs to $2.30! Unfortunately the lady on register noticed this and called over a supervisor but I imagine that if you went through a self serve checkout this wouldn't show up. I'm not planning on going back to another store to check it out but if anyone was thinking of picking some soft drink cans up this might be worth a shot. Stirling Central WA Woolworths.
