I pay with Canadian money, because I'm a Canadian who buys from stores in Canada.
That was easy to do in Ontario Wal-Mart stores.
But then they put up self-check-outs that only accepted credit and debit cards—maybe because they're in cahoots with the banks and the NSA/wp:CSEC.
Then I had to use a cashier.
So I went to Wal-Mart fewer times as I didn't like to wait (as well as the increased prices during and after Covid-19).
Now they have a person at the self-checkout who will scan my stuff and accept my cash.
It seems that Wal-Mart adapted—somewhat—to people like me: people who pay with cash.
Still, I do more purchases at Food Basics and Dollarama because their self-check-outs accept cash, including pockets full of loose change that I purposely carry when I go there.
All zero Walmarts in this country. Their attempt of invading our market was crushed between being to expensive, having shitty products, and working labor protection laws.
