3% isn't exciting but you don't get much better than this for Bunnings, and not for unlimited conversion.
in-store only and must spend more than the full value less up to $9.95 in change. However in-store you can purchase the gift cards that have a pin and can be used online, using these gift cards. So you can always straight convert these to online gift cards with a trip to Bunnings, or top off your order in store with a few gift cards if you don't spend the full amount.
maybe this helps someone with a big project coming up.
Speaking of lower value gift cards, I find that Bunnings gift cards provides one of the better conversions for credit card rewards points. That can be one of the options to grab Bunnings GC's.
