More Quantitative Confusion
I’m pretty sure printer ink is a huge scam to begin with, and stuff like this doesn’t help.
I went to purchase some ink and looking to minimize my time spent in office supplies stores, I thought I’d buy a two-pack. “We’re out of the two-pack,” the helpful employee said, “but this is the XL. It’s the same price as the two-pack, and it has 3 times as much ink as the single cartridge.”
So after my purchase, I felt compelled to perform a side-by-side comparison.
