Resale shops will see to it that the item is attractively displayed, plus you don't have to spend your weekend tagging and organizing merchandise or having strangers and nosy neighbors trampling your yard.
And if a buyer bounces a check, "it's not your problem," Meyer says.
Ask how the shop's consignment process works because every store tends to be a little different, says Meyer. Some stores, especially those that sell clothing for kids or teens, will offer the option of giving you cash upfront. Some let you choose between getting less cash now and a potentially larger sum when the item sells.
With some stores, if an item doesn't sell you can reclaim it. With others, it may become the property of the shop or be donated to charity. "Find out what your options are and understand everything completely," says Meyer.
The goods that sell best at consignment shops: "Almost any kind of goods," she says, especially gently used clothing, kids' toys, furniture, costume jewelry, DVDs, CDs or sporting goods.
EBay: Sometimes described as the world's largest garage sale, you can find a buyer for just about anything on eBay. A case in point: Four toilets once owned by Jerry Garcia sold for a little more than $5,000 in 2005.
At the same time, "You shouldn't treat eBay like a rummage sale," says Brad Schepp, co-author of "eBay PowerSeller Secrets: Insider Tips from eBay's Most Successful Sellers." "Selling takes work."
If you want to get a good price for your stuff, put in a little time doing some research and limit yourself to items you can sell and ship fairly easily, he says.
Skip antiques and collectibles until you've learned more about the items and have a little more eBay experience.
It can be a great venue for upscale or specialty clothing like furs or designer dresses or children's clothing from recognized labels, says G.G. Carbone, author of "How to Make a Fortune with Other People's Junk."
If you want top dollar, it also pays to be time-sensitive, she says. Spring is the wrong time of year for fur, but "it's a perfect time to put prom dresses on eBay," Carbone says.
EBay stores: These are often billed as an option that offers the convenience of a consignment store with the marketing advantages of eBay. You take your items to the store and the purveyor sells the items on eBay, ships them to the buyers, accepts and vets payments and gives you your cut of the purchase price. (You can monitor the selling process from your home computer.)
"I think they're great," says Schepp. "They're going to do a little triage on what someone walks in with."
