It's the weekend to stock up on back-to-school supplies in Missouri. The Missouri Department of Revenue says the state's sales tax holiday begins Friday and runs through Sunday. Back-to-school items like clothes, supplies and computers can all be purchased without paying the tax.
However, before you make the drive from Illinois, you should know that some towns will still collect city sales tax on the exempt items. Add that to the price of gasoline to get there and it might be a break even trip.
