What our customers are saying
FAQ
Our expert staff answers customer's most asked questions.
Are there discounts on Open Box products?
Yes, we offer discounts on Open Box items. However, these prices are often too low to advertise online as they fall below Minimum Advertised Price (MAP) guidelines. Contact us directly for the best deals on Open Box products.
Do you offer warranties?
Yes. We offer extended warranties at check-out.
Should I cover my spa or pool with a custom spa cover or solar pool cover if I am heating my pool?
Yes, it is advisable to cover your pool when heating it. Failure to do so allows generated heat to escape, causing the heater to work harder and resulting in higher heating costs. Consider using a custom spa cover or solar pool cover to optimize the efficiency of your heating system.
