Many Altus merchants are getting ready for a crazy shopping weekend, with many local stores dropping prices for the sales-tax free “Crazy Days” weekend. Lady Austin’s Store Manager Leslie Briscoe changes a sign for discounted items in her store. Oklahoma is holding a sales tax holiday this weekend giving shoppers the opportunity to purchase certain clothing and shoes free of sales tax. This includes state and any local sales taxes. Retailers are required to participate and may not charge tax on items that are legally tax-exempt during the sales tax holiday.
