For the 2018 season, I am offering an early payment option. If it's easier for you, you can make a one time payment and get a free spray. Some of my customers have asked to pay upfront and I want to give a discount for them. Contact me at 910-309-5103 and I'll get you on the schedule to spray every 3 weeks. Pay for 9 sprays and get the 10th for free!
