I've been a occasional buyer at Harbor Freight. I will occasionally shop there still, if necessary, but I, too, am making a point of not buying from China.
I just pulled out my non-Harbor Freight generator, a Champion one. "Designed and Engineered in the USA and North America!" Oh look, made in China.
I was recently looking for a new guitar and amp. I picked a guitar made in Korea (from an American Company.) The company also has lines made in the USA (more expensive than I need for at least the foreseeable future), Japan (more expensive than I need for at least the foreseeable future- it's also top of the line, just different lines), and China.
I specifically avoided the Chinese made lines.
Looking at Amps, I looked at a lot of "American" companies... who make all their amps in China. It looks like I'll be going with a "Japanese" amp, made in Malaysia.
I'm not going to ONLY buy American, but I am going to stop buying China, even if it's from an "American" company.
I've also noticed it's not easy to determine where things are made. It's possible and as you can tell, I've done it, but it's not out there on their websites.
I'm going to do the same for all my purchases, where possible. If it costs me 50% more, so be it. But some products cannot be had aside from Chinese-made because they have driven out all competitors with anti-competitive practices that would get a private company sued. (Oh, and slave labor. I don't think a private company would get away with that, either.)
