Most retailers use Black Friday, the day after Thanksgiving, to kick off their biggest shopping season of the year, even if they also move the sales kickoff around a bit. For stores that sell home-improvement and gardening supplies, spring is their biggest shopping season. That impeccable logic led to the invention of Spring Black Friday, which we first noticed in 2013. It isn’t going away.

We’d like to say that this is a silly self-promotional yet self-effacing April Fool’s Day prank, but the trend of spring Black Fridays at home-improvement stores is a few years old, and appears on different days of the calendar. Nope, it’s real, and back for another season at Lowe’s.

Courtesy of reader Henry, here’s an e-mail solicitation that Lowe’s sent out today. Other home improvement stores will join in soon if they haven’t already. Last year, Home Depot had an entire Spring Cyber Week.

Once the spring planting season is over, there’s just a few short months until Black Friday in July begins at Target and other retailers.
