Pricing and checkout
Color stickers plus one price per color is the fastest way to run a garage sale: buyers know the price at a glance and you add up colors instead of haggling over every tag.
Best time to hold a sale
Summer (June-August, dodging local rainfall patterns) (our general guidance, not a city rule; not yet backed by a source)
