Vodafone's $29 recharge is now $26 at Coles Supermarket. As mentioned in the catalogue it states "offer only available at participating Coles supermarkets". These recharges have a 30 credit expiry. This is down and staying down, so it is not on special.
Please refer to catalogue for stimulus (page 6) as linked. Could not find this deal anywhere on the Coles site.
If I'm not mistaken, all Vodafone recharges are always 10% off at Woolworths and their other stores (Dick Smith, BigW, etc) making the $29 cap recharge $26.10
