Dynamic pricing means prices go down as well as up. So this is conclusive evidence that either (a) she's stupid, (b) she's dishonest, or (c) both. The strange thing is, I genuinely can't guess which it is. Could she lie this overtly?

We should all be worried about "dynamic pricing." That's when companies change their prices in real time. If it's hot out, the cost of ice cream could go up. If it's cold, tea bags could go up. It's a way for giant companies to squeeze you even more.
