I just Googled and found that Verbatims are made in Taiwan, India, and Singapore, but not in China; I wonder how that changes the equation?
There are a few comments to make with your question. First, although I have no way of verifying this, the cheap Verbatim disks may have been fake or stolen. Second, there have been some user complaints about Verbatim disks made outside of Taiwan, specifically India. Again, I have no personal experience with this, or another way of substantiating such claims. But if any (and particularly the former) of these possibilities are even partially true, that could be a basis for excessively cheap offers. I consider that more likely than an explanation rooted in Chinese currency policies, as this wouldn't account for the price difference seen.
