Ordered a water heater at a very low price over another with a time limited sale. A couple days later they canceled my purchase and pointed to some mistake "policy". Annoying but not the end of the world and they corrected the online price.
A month or 2 later, same unit reappears with same price. Same result.
These people are using pricing they won't honor to drive traffic to their site, wasting buyer's time and opportunity. Avoid them so they stop misusing search utilities!
