I've read recently on another forum that vendors are falling prey to scams involving fake screenshots of transactions. I'd say it's not so much of an issue for many if using direct deposit via Osko etc, but for sums larger than the banks allow using NPP then it could result in the loss of many $ thousands. This is a new thing for me, no doubt many here are already aware of it, but for some it may be new news. Apparently there are apps that can create fake screenshots of transactions, I haven't confirmed that or not. Sellers beware.
