Quality of Service/Products
I read a lot of online shopping horror stories, so here's a good review on Sierra Trading Post (www.sierratradingpost.com). I order online from them quite often and have been very satisfied with the quality of their products, their prices, and shipping times.
They carry name brand products at great prices and they have a clearance/closeout section that is usually discounted anywhere from 50-75% off. Their merchandise is geared more for outdoor activities, however there are other things like outdoor patio furniture, bedding, etc.
They also have a live chat option that you can ask questions before purchasing. Once you receive your order, if you are not completely satisfied, any item can be returned, no questions asked, for immediate online credit. The account profile that is set up for you keeps track of all of your orders, any returns, credits, etc.
