I bought a self supporting clothes line (kind of an inverted umbrella on a stand) from Costco's wholesale website. The site was easy to use and entering keywords brought up a good selection including comprehensive details and specification.
I had no real trouble with navigating the checkout procedure though I'm relatively new to on-line shopping. Their prices were significantly lower than other on-line outlets. The product arrived on schedule and I was notified at each step of the shipping process.
I have not had any reason to purchase anything from Costco since August, but I have no reservations about doing so in the future. Though there is always room for improvement, my experience was very positive.
