The thing that annoyed me about that was the sales rep didn't *do* anything to close the sale. Normally, the registration is only supposed to happen if they got an FAE to help with the design-win, e.g. some distributors have guys who can come on-site to help debug code or review schematics. This was just a quotation, and the registration was claimed.
Ultimately, you could try to source components at the lower "china price" but they have to go through the gray market, so the purchaser and producer identities are lost. But doing that carries its own risks.
