Garage sales are overwhelmingly friendly, neighbourly events — and a tiny bit of preparation keeps them that way. The risks are mundane (a wandering cash box, an open front door) and every one of them is preventable with habits that cost nothing.
Cash rules
- Wear your money in an apron or fanny pack — never a box on a table
- Keep only working change on you; move accumulating bills inside every hour or two
- Count change out loud, bill by bill — it prevents both mistakes and short-change artists
- Watch for the classic: a large bill for a tiny purchase during your busiest moment. It's fine to say 'sorry, no change for hundreds'
- Prefer e-transfer/Venmo for items over $100 — confirm it arrived before the item leaves
Your home
- Lock every door that isn't the sale area, including the inside door from the garage
- No bathroom access, no exceptions — point to the nearest gas station
- Move valuables (and anything NOT for sale) out of sight before opening
- Two people minimum: one at the money, one circulating and answering questions
- Don't advertise your absence: skip 'moving overseas next week' in the listing copy
The driveway itself
The most likely incident at any garage sale is a trip or a dropped box, not a theft. Keep walking lanes wide, cords taped down, breakables away from table edges and toddler height, and heavy furniture stable enough to survive being leaned on. If it rains, dry the smooth concrete — wet garage floors are genuinely slippery.
Online, the same common sense applies: keep communication inside the listing's messaging rather than posting your phone number publicly — your listing handles buyer questions without exposing your contact details.
Frequently asked questions
How do you keep money safe at a garage sale?
Wear it — apron or fanny pack — and skim large bills into the house every hour. Never leave a cash box unattended, count change out loud, and feel free to refuse $100 bills on small purchases.
Should you let people into your house during a garage sale?
No. Lock all doors outside the sale area and politely decline bathroom requests. Anything you want to sell from inside, carry out to the driveway instead.
Are garage sale scams common?
Rare, but the known ones are simple: short-change confusion during rush moments, counterfeit large bills, and 'I'll pay you the rest later' on big items. Counting out loud, declining hundreds, and full payment before pickup prevents all three.
