Are we the baddies?

I went to Walmart twice last week, Tuesday and Friday. Passed by the chips aisle twice and the price on Friday was over a dollar higher per-bag. They've got those fancy e-ink screen price-tags now and I guess they're doing surge pricing. I'm tired of this shit.

It's called "dynamic pricing" and it's everywhere. https://de.wikipedia.org/wiki/Dynamic_Pricing
