5 Things You Should Never Buy at a Yard Sale

Pass on the used cribs, playpens, car seats, and other baby gear.  You could be putting your baby at risk because of the safety hazards of some older toys.  Also, you shouldn't use a crib that is older than 10 years old because they have design flaws.

Older helmets may offer less protection than newer models.  And, you're supposed to replace a helmet every time you've crashed while wearing one.   “Damage may not be evident. Cheap helmets are available new.” - CheatSheet.com

Does this even need an explanation? BED BUGS.  These pests are found in every state and can be difficult to get rid of. Keep your home bug-free by only buying new mattresses, and stay away from upholstered furniture for the same reason. Plus, used mattresses can come with stains and odors that are hard to remove, and may carry pet dander or mold. Even if it looks like a great deal, skip it.

The chemicals used to make the coating may not be safe.  If you're set on a used set of pots and pans, make sure that there is no chipping in the coating.  The average lifespan of a non-stick pan is between three and five years.

Even if an item still works (make sure to test it before buying), there’s a good chance that a better, cheaper model is available somewhere else.  “If something is battery operated and it doesn’t work, there is a good chance the batteries that are in it have corroded, making it unusable.” - CheatSheet.com
