Recently I decided to declutter my home and post items on Ebay.  I made $2000 in a few months selling on Ebay, here's how! 

Choose the right products. New or very gently used sell better. Name brands like   Gap,   Coach,   iPhone,  Playstation, etc. And items with original packaging are easier to sell. 

Consumer tech from big name brands 
Anything with Apple,   Samsung or   Sony. Recently I sold an  iPad mini for $100! That is money in my pocket.  

Here are some of the items I have sold on Ebay:

• Geotrax
• LeapPad + 7 books and carrying case
• Build a Bear coupons
• Gymboree coupons
• LEGO
• Fisher Price
• Disney toys

New in package usually sells the best, but gently worn is ok too. Think name brands for clothing:

• Gap
• Justice
• Janie and Jack
• Osh Kosh
• Hanna Andersson
• Children's Place
• Gymboree

Add the word "vintage" to your description for more sales. I have sold:

• dolls
•  dishes
• salt and pepper shakers
• vintage Lincoln Logs
• vintage board games
• stamp collections
• antique toys
• antique books (especially 1st edition)

Try visiting your local thrift shops or Goodwill for finds that would sell on Ebay. Also check out yard sales, you never know what you could find! Look for: 

• Vintage accessories: Gloves, handbags, scarves, belts
• Brooches, pins
• Keychains - odd, vintage, music/sports/auto related
• Small electronics, calculators, cameras - vintage, best if with box and cables
• Early video games, especially the little handheld ones, best with box/instructions, check if they work w/new batteries
• Car-related items: keychains, accessories, etc.
• Charm bracelets, charms, pendants: odd themes, can be sold as is or separately as charms
• Costume jewelry: doesn't have to be designer, well made, unusual, odd themes
• Collectible glasses (McDonald's, etc.), the older the better
• Pens: vintage, older, unusual, again you should know what you're looking for.
• Linens: aprons, handkerchiefs, curtains, sheets, vintage, unusual, check condition carefully
• Buttons, fabric, other notions: odd, vintage, collectible
• Christmas items: ornaments, music, jewelry, decorations, again Condition, Vintage, Unusual.
• Sports memorabilia - pins, keychains, mugs, odd housewares, etc.
• Fast Food toys, the older the better (<2000 at least), best if still in packaging
• Tools/housewares- vintage, odd/unusual, best with box/cords/instructions.

• Choose the right category for your item-try to be as specific as possible so that potential buyers will be able to find your listing.
• Write an accurate description-brand name in the title, along with the condition.  Be as specific about the details as possible.  Buyers want to know exactly what they are buying.
• Take excellent photos-for the best shots, use indirect daylight (not bright sun). You don't need a fancy camera, I use my iPhone and it works great.
• Make sure your item fits in the box.  I recommend selling items that fit in USPS Flat Rate shipping.
• Respect the buyers-once your auction is live, be sure to pay attention to any questions.
• Never ship before payment! This is one of the #1 rules. Most buyers will pay quickly but never ship an item until you have received your payment!  Be sure to send out an invoice and a gentle reminder after a few days. If you don't get resolution, be sure to contact Ebay.
• Ship your item as soon as possible–as soon as you’ve been paid, make an effort to ship out your item. You can pay for shipping and print your label at home.  If you already have the box then all you have to do is tape it up, put on the pre-paid label, & let your mail carrier pick it up or drop it off at the nearest post office!
• Give feedback–whether positive or negative, leave feedback on your buyer’s feedback page.
