Costco's Delivery service through a third party is terrible. I had them deliver 3 times and was told by Costco's "Conceirge" services that they will follow up and fix the problem each time. However, the delivery Service, JB Hunt, made no attempt to sincerely do the dishwahser installation properly. Their comments were distressing - The first one said that he had to do 17 deliveries and hence could not spend much time on one install !!!. The installation was not done properly. The third time, the installers forgot to put in the power plug and started blaming the product. Their installer's comment - "I am done with this install". Once they discovered that the plug was not put in, the installer did not check leveling or anything and just moved on saying that he was did everything he could! Best Buy installers professionally installed the same product in the first try. Very impressed with Best Buy's installation service Lone Star installation.
