Gold standard at this point in time would be deflationary (if the population is growing faster than new gold is being mined, at least). Deflation incentivizes money hoarding, and disincentivizes loans and investments. Capitalism basically breaks down during times of deflation (investments dry up, people stop spending money on things they don’t absolutely need, companies lay off or go out of business, unemployment rises).
I usually order form Amazon for convenience, but sometimes use shopping.google.com. I look up every site before ordering though. Some of the sites that show up in the results are sketchy or deceptive. I also sometimes use Ebay if I’m ok with buying something used, or something very cheap of questionable quality (from people who I’m guessing are just resellers of Alibaba crap).
