I hope you all have a blast at LSS garage sales! I am really going to miss selling at this next one - the spots are filled already. But I may just go as a shopper
Every time I've gone, they've had 30 people lined up at the door before opening, and it's just a blast - and well worth it. I've made from $300 to $600. Be sure to price everything clearly. I made up signs and grouped items accordingly. Sometimes, it'd just be anything in a box for $1 or $2. I priced low but made up for it with volume.
Another thing at these sales is that we'd pre-shop at each other's tables while setting up. Now... that can kind of instantly put a dent in your profits, but it's also a chance to get some good bargains before the "real" shoppers arrive. And even if you don't buy, it's a nice way to meet everyone you'll be spending the day with - and they may shop at your table, too!
