My local supermarket keeps trying to encourage me to download their app to scan my shop as I go.
Exactly. That's called marketing you to do the work for them for free. Then there's customer surveys. I ask them how much they will pay me for my time since I can't work for them for free. That halts it, lol.
Since you mention the scanning for cheaper elsewhere, they do that price matching thing at several grocery stores, so that must be what they are doing. It's all so bizarre. Here, most don't look up from their phones, yet are able to navigate an unseen obstacle course.
For however long it lasts
That would be the key thing. Depends on which province one is in here, as to what is lifted, but nothing has been completely lifted. One province is already warning that restrictions will return in the fall. I wonder how they can predict so well. I need that crystal ball, LOL.
