On the bottom of my Woolies petrol receipt I noticed a bit saying that I could get 40% off a pack of 8x200ml coke cans if I presented the receipt.
As coke is the favoured brew for the fishing trips I went into the Woolies shop, and got the pack of coke, (the label said 2 for $8 but I wanted only one).
At the register the bar code didn’t work. Eventually somebody in the know said I had to buy it at the petrol station.
At the petrol station I found the coke cost $9.99 for the pack, when he scanned the receipt it came down to $5.99
Out of interest I went back to Woolies, lifted the 2 for $8 label, and found the price was $5.99 for one pack.
If that’s not a scam, it is pretty close to it.
Caveat emptor etc.
