Anecdotally, I do not know a single person that has ever checked the "Made in X" tag on a product before buying it. Even the most nationalistic folks I know.

Some people might see an online advert where the vendor is pushing the "made domestically" tagline hard, and it might even get them to buy that product, which probably had 80% of the components made in China anyway. I've never seen somebody stopped from buying a product because it was manufactured in China though.
