When I first started to sell online, there were some things that I found out pretty fast.  Here’s a few of them:

The weight of an item matters.  This will be a major factor of how much shipping and handling that you charge for an item.  The weight will be a combination of the box, packing materials and the item itself.  A good rule of thumb is to find a box that is a little bigger than the item to you are shipping, but not too big—it will definitely cost you more.

There are restrictions on what items can be sold.  Each website that you sell on will tell you what you can and CAN NOT sell, and each selling website will tell you when you set up your seller’s account.  If you already have seller’s account, you can find this pretty fast in the HELP section of the website.

Use social media to your benefit.  Facebook, Twitter and even Pinterest come in very handy when you want to spread the word that you have listed an item—I usually include a photo when I am on one of these sites so people can also see what’s for sale.

This is just a few of the things to consider when you sell an item online.  What other things have you found out?
