Although we don't carry Coleman spas, we used to carry Infiniti spas which are made by Colemans parent company Maax Spas. We carry D-1 as well & have for nearly 20 years. Mainly the price points that each line offers and the quality of the product. Plus you have the best of both worlds to offer a customer, full foam and Thermal lock, unique features each brand carries, brand recognition..etc.
