It's not much fun visiting a grocery store at the moment, and the only marketing retailers can be doing is focusing on prices or the efforts of their staff on the frontline. There's certainly nothing happy to be said about the customer experience of standing in a physically distanced line to get in and dodging other shoppers while trying to source your toilet paper and hand sanitizer.

So kudos to Canadian chain No Frills in its attempt to entertain with a rap video reminding customers of the new "rules" of shopping in the time of coronavirus. Created via John St, the track, "A Cart Apart" gets the messages across—don't hoard, don't over-handle the produce and keep six feet apart—without being preachy. 

There's also a charitable element—for every view, No Frills is donating a dollar to President's Choice Children's Charity, to a maximum of $50,000.
