I know a lot of people here got these reloadable cards when they were going free. It seems now this product has been "killed" and won't be replaced when they expire. You cannot buy these anymore, however you can use an existing one until expiry.
I have been using this for both convenience and getting FlyBuys from my larger purchases. These days I prefer not to have a "debt" credit card, due to having accrued debt in the past and the torture of paying it off (never again!). It's also handy knowing you have an extra card in the wallet.
So my questions are:
Have you been getting value from your Coles Reloadable Mastercard?
Have you "abused" it? ie. stacked dealed to maximise points?
Will you miss it?
ETA: Update to save you searching, here is what the website now says:
Coles Prepaid Cards
Important: The Coles Reloadable Mastercard and the Coles Online Mastercard are no longer available to new customers. Existing customers can continue to use their cards as normal and access their account online through the prepaid service centre.
