But this is not good enough for OzBargain, so we are going to get some money back. The Good Guys is selling the same product for $179, so first place an online Click & Collect order to get your $20 store credit. Next we make a claim against The Good Guys' 30-day 120% price guarantee to receive $60 back in EFTPOS card or store credit.
TGG's price guarantee claim page asks you take a screen capture of the competitor's advertised price. Here is a copy I prepared earlier.
JB may run out of stock before you complete a claim for the price difference. If you can forgo the $20 C&C store credit, a surer bet is to check stock level at JB immediately before buying the food processor in-store at TGG. JB stock level checker is available on its web page above the "Add to Cart" button.
Pay The Good Guys: $179
Receive store credit: $20
Receive 120% of the price difference ($179-$129=$50): $50 x 120% = $60
Final telly: pay $119 to get food processor and $20 store credit
