Ebay
If you have items you’re willing to part with, you can put them up
for sale on eBay with the Buy It Now option. With Buy It Now, you don’t
have to wait days for an auction to end. If someone sees your item and
likes your price, they can buy it right then and you will most likely
get an instant Paypal payment.
If there is a lot of competition for the item you’re wanting to sell,
study the prices of the other items and make sure yours is lowest. You
might be willing to take a bit of a loss if you’re truly that desperate
to get the cash ASAP.
Craiglist
If you don’t have an eBay or a Facebook account, you can post your
items on the Craigslist site for your local area instead. Your ad will
go live shortly after you post it, and just like with Facebook and eBay,
there’s a good chance you’ll sell fast if you’ve done your research and
priced very competitively.
Please be careful whenever meeting strangers for these kinds of
transactions. If possible, make sure you’re meeting up in a public place
with lots of people around.
Etsy
This is another extremely popular online marketplace for people with
crafty or vintage items to get rid of. Setting up an account is free and
if your items sell, you’ll get paid to Paypal instantly. Browse around
to see what others post to get ideas for what you can sell there, take
good pictures, and price your items very competitively to see some quick
sales (and quick money).
