My tip? eBay's Want It Now section. People
Another use: I browse the ads to see if I have anything someone else wants. I've got a ton of books, dear to me, but not too special to sell! My husband occasionally has an opportunity to sell very specialized construction parts and tools. I've even seen people asking for someone to handcrochet, knit, or sew them a special blanket or item.
Best of all, you won't end up paying a listing fee for junk you weren't able to sell, then try to decide whether to dump it in the Goodwill box or list again.
Works for Me!
