Recently purchased a bench vice from Bunnings. My wife holds up the receipt and asks if I want to keep it. I laugh, and say "It's a vice, it's not going to break." Mentally I picture a blacksmith banging on his anvil and having it split in two.
Three days later, I stick a steel rod in the vice and begin bending it. Snap. Cast iron body of vice snaps in half. I don't think I'm game to try returning it to Bunnings without a receipt. I also feel like a complete dill for having laughed at my wife.
I've made it a habit to save all receipts… Why dont you buy a new one and return the broken one with the new invoice?
Also, bunnings can locate your receipt if you can provide details…
