As we move into mid-July, keep a close eye on office supply and big box store sales flyers. Traditionally, these stores have some great deals on paper, presentation folders, glue and other school supplies that are commonly used in the office.
So far, I've seen paper for four dollars, glue for eighteen cents and Purell for five cents. Stocking up now on supplies like these means you can save big later in the year, when they will cost much more.
By the way, if you have a family friendly business, don't overlook other cheap school supplies, like crayons and pencils. They serve two purposes - you can set up a kid's area so they can color and draw while their parents shop and you can put together inexpensive back to school goodie bags (with your company information on them, of course) to donate to local schools that have students from low income families.
