Don't forget to check your emails, because Mars has paid up anyway and given registrants from (http://www.ozbargain.com.au/node/98094) a free mars bar this weekend at Caltex Woolies…
The barcode I was given was 9300xx2036x84 (x meaning hidden number)
Did you guys get the same??
Same barcode I think, but note that there is also a Unique Code in red above the barcoded section. Also note that it's not available at all Woolworths Petrol stations, only particular ones; a very restricted list.
