Interestingly, despite people spending less on Amazon, they haven’t gone back to buying stuff at local retailers. That’s what local retailers hoped for and is why they badger their states to make Amazon charge state sales tax. Instead, people simply buy things from other online retailers to avoid the sales tax. (And good for them for doing that!)
Personally, I’ve been buying a lot less stuff from Amazon this year, and I’m from a state where they have to charge sales tax. This isn’t so much due to the sales tax, and just that there haven’t been many games I need to get this year, and I haven’t needed much in the way of computer hardware either. Still, I know that having to scrape up even more money because of sales tax is annoying.
