Bob, dealing with the Chinese is a different matter then what most of us consider good business manors. They dont look at things the way we do and have a very cold, distant attitude towards others, even within their own society (or their own kind).
Google "dealing with the Chinese" its a real eye opener.
I understand your take on this Banggood thing, as I have had some bad dealings with some other Chinese vendors. But as is true in any society you will have shady people to contend with, heck, we even have a few dirt bags here in the good ol USA
Sometimes its just a lesson learned, and there are some really good vendors over there. I mostly stay with HK and endure the wait, at least they are honest and have great customer support.
I am also on a disability budget, so I understand what your going through and dealing with crooks is not acceptable.
