How do they stay in business?

I will add my recent CW online experience, I was looking for a 25" x 19" single basin kitchen sink to replace the stock double basin kitchen sink in our travel trailer. (DW wanted a single bowl sink) I searched the internet for a couple of days, Ebay, Amazon, bunches of online RV parts suppliers, and then I thought I would check CW online and low and behold they beat the lowest price I had found by about $20.00 and free shipping. Needless to say I ordered from CW and received the sink in 4 or 5 days counting the weekend. I was happy with that and I will order from them again if they have what I am looking for and it is cheaper that anywhere else I look. CW is like any other retailer some things you may find cheaper and some things you may not find cheaper, that is why it is best to shop around. The same goes for shipping charges some places are cheaper than others, shop around.
