@PopulationOne-ish asks
I'm $15 short of free shipping and keep adding cards I barely want. Am I saving money here?
Jeff answers
I'd compare the original cart plus postage with the expanded cart's full total. If the extra cards aren't on your list, the shipping offer may be increasing your spending. Our app can help price actual wants, but you don't need to invent wants to unlock a checkout badge.
