The one thing about garage sales if your trying to get flea market or retail prices dont bother having one. I literally had people paying me in pennies for .50cent items.
I would have items brand new in packaging for cheap cheap prices and people would still try to haggle me down to a buck.
I accidentally had a pair of brand new coach shoes i hadn't planned on selling at the sale but on ebay. someone asked i told them $8 they wnated them for two these had never been worn. wound up getting like $55 plus shipping on ebay.
garage sales basically you have to just take whatever somnene is willing to pay usually under $2 or your wasting your time. I normally make my profit and then hav ea garage sale and am basically willing to take anytghing as otherwise its going to good will.
I made like $150 my last garage sale i think my highest priced single item was like $10. Sold an almost full set of noritake china for like $9 sites like replacements sell one piece for like $18-$26 but if you cant sel it on ebay or resale shop what else you going to do with it.
my best customers were the soccer mom types who werent totally cheap. i had TONS of name brand clothes limited, guess, forever 21, bebe, dkny, d&g and was basically telling theese moms who wnatd a bunch of stuff fill up a garbage bag and we'll come to a fair price.
