I don't get mad at shit like this, I just don't buy.
Rage gets you nothing from these pricing schemes. Letting the company go broke does.
I solved this problem, with regards to coffee, permanently for myself by getting a Timemore S3 and an Aeropress Go. All said that $200 CAD invested 5 years ago has save me hundreds in coffee bills, and now I can make a fresh cup at the campsite, road side, anywhere. All I need is hot water.
