Stunning to see what a little outside motivation can do, isn't it?
I cancelled because I started to realize Amazon is hardly ever the cheapest price anymore, and most other companies now offer 2-3 day shipping for free. I order direct and support the actual company making the product instead of giving money to a monopoly with terrible ethics.
It's not consumerism when when I pay US$119/year for the privilege. Then it becomes, "meet your SLA that I'm paying money for, assholes."
