Apparently Bunnings have no business sense then.
If they are allowing people to just add a cost onto their business for no benefit then yes. Also it may just be the staff member, rather than company policy.
It is still a common method of fraud. Bunnings may be just making so much profit that they do not care. Plus WOW will have more leverage with the banks than most companies.
I used to get a lot of people trying it on. It was a pain in the bum as they would also waste a lot of time trying to get reversals. Plus money that is not yours has to be kept for the banks who would come a knocking. Sometimes the banks would also try and extract other fees from us. And if you pay to another card and the original card was stolen, or was a transaction that the card owner did not actually make, or just was not paid, the bank recovers the amount from you.
At up to $10,000 each time it is not something to muck around with.
I changed software so that online payments required more validation and that removed the problem. I still get scammers though, but as I have removed the automatic online payment without validation, they do not get past the first email or phone call.
Manually refunding to a different bank account or credit card is also extra work. Refunding to the original card is just a click with everything else just automatic in the accounting software.
I only refund to a different means in exceptional circumstances. Plus they will need to invoice me and I will only pay into a bank account and not a CC.
