In Canada it's tap to pay for ~8 years now, never saw a QR code to pay. However when I go in USA, every stores is tap to pay, except one, there's one store in USA where there is no tap, it's Walmart, inconcevable.
Loblaws branded stores disappeared from QC years ago. In Québec, Métro is pretty expensive, like IGA or Provigo. The cheapest groceries are Maxi (yeah, it's Loblaws group) and SuperC (Metro group). But for me, all fruits/vegetable comes from local greengrocers, who also sell various ham/cold cuts and lot of cheese, sometimes for 50% of the price of groceries, and it's fresh cut. Else for some bulks there's bulk barn, and Costco, or sometimes even Amazon, a family box size cereal is $10.99 at IGA and the same one is $5.49 on Amazon.
it should be in your MS online account as someone wrote, but in case of, I always save it on a USB key, hidden somewhere. You can also print it, or take a picture of it with your phone. Because there is no way to get it back.
I have bought hundreds of stuff on AE, it's ok, especially for stuff that are less than $10 that local sellers sell for like $40 for the exact same thing. I got some items in less than a week in Caanda.
uhoh, and wait for the time when the user will update his BIOS, that resets TPM2, and at reboot bitlocker asks for the 48 digits key to decrypt hard drive, that the user never saved...
