I used to laugh at walking into the grocery store of big box discounter and see school supplies on the shelf the morning after 4th of July fireworks. It turns out they aren’t just filling empty space, but filling a big market. While the days of waiting until after Labor Day for school to start is a thing of the past for most districts, there turns out to be 3 major waves of Back To School shopping. The first takes place in mid-July, with early birds picking out the trendiest most fashionable items before they are picked over. The second is the mid-August school is coming wave and of course, the largest wave is that last minute, school starts tomorrow wave. The folks at Microsoft/Bing have put together this infographic sharing when and how we should be marketing for Back to School.
