So far it is pretty obvious that the "sales" people whom argue prices with you have no idea what they are selling. A couple times now I have been looking to get some stings of the WS2801 stuff and after arguing price for a day or so they get it down to what I am looking to pay and then when I ask for full confirmation of what I am buying they have switched it to the WS2811 without even telling me. I fear something similar to that is going to happen when/if i ever do go though with such a purchase. Would paypal/my bank protect me if such a thing happens? I think Alibaba has an escro system... is that worth relying on?
