Great service!

Very happy! I was a little hesitant when looking at other reviews, but I called to ask questions and the man was so helpful and knowledgeable that I decided to order the heater from them because of their great price. The shipment took exactly as long as he had said (5-7 days) and the delivery company contacted me the day before as promised to schedule the time. Delivery went smooth and the product was packed and protected well and was in perfect undamaged condition with all paperwork and instructions included. My husband installed the heater a few days ago and it works great. Very satisfied and would definitely order from Best Buy Pool Supply again.
