Use your Coles 4c discount coupon and spend $40 or more on a Telstra prepaid recharge to save 10C per litre on fuel at Coles express.
Probably fairly limited in terms of those who can use it however if you need Telstra credit and fuel its decent.
Mod - edited title.
I don't use Telstra. Anyhow would this special be used together with 4c discount from coles credit card and the 2c discount when buy $2 in coles express? In that case the combination could become 16c/L in total.
Part of your answer is - Its 4c regular plus an extra 6c - dont know about the $2 spend deal
While it's a deal not sure how good this is. Lets say average fuel fill is 50 litres then 6c extra times 50 = $3.00 at 100 litres its $6.00 which is either 7.5% or 15% off (if my maths correct) not a huge savings
not convenient coz need to buy $40 telstra to get 10c
