Just had a proper look at the Bunnings Rewards setup.
You earn 1 point per $1 spent, and 500 points gets you a $5 voucher, which basically works out to 1% back.
Don't get me wrong, I still love Bunnings - they're easily the cheapest around and the staff are always super nice. The app is also genuinely handy for keeping digital receipts in one place for returns or warranty stuff
Savings-wise though, spending five hundred bucks just to get a fiver back is a bit eh haha
I tried registering on the day of launch, and kept trying for about a week or so thereafter, but it just wouldn't work - kept going round in circles of re-directs.
Given the cluelessness of their tech / web people, I'm staying clear for a good while, as that indicates its a quick bodge-job behind the scenes, and potentially not at all secure.
Just not worth it for 1% off.
