1. Choose your categories carefully

Again, this is a question of not overspending, especially if you're selling small items that aren't individually worth that much. Depending on how you initially describe it, eBay will, by default, suggest likely categories that your item may fit. The trap with category listings is that adding each additional one doubles your insertion fee. Note that it will also double your upgrade fees, for pictures and the like.

2. Use your own picture storage

Your first picture with eBay is free, but there's nothing stopping you using your own online picture storage instead. Why would you want to? Well, because eBay will charge you 25c for each additional picture. Hosting your own pictures will also give you absolute control over what's shown in a listing, including when you want to take photos down or change them. Don't use pictures hosted on sites out of your control, or you might receive a nasty surprise should someone change the content.

3. RELIST unsold items.

You have already paid the insertion cost of the listing, so if it doesn’t sell, eBay will allow you to RELIST FREE.

If you click on UNSOLD ITEMS to the left of your My Ebay page you will notice that all the items you haven't sold are in there. Some will say sell similar and some say Re-list.

The ones that say Re-list means you are entitled to credits if the item sells so just tick all the little empty boxes on the ones you want to list (that say re-list) scroll to the bottom and hit Re-list. You will notice next time you go into the unsold items page they will have a blue circle with an arrow, which means they were re listed , you can then tick all them boxes and delete them.

The items that say Sell Similar means you are NOT entitled to a credit if it sells the next time, there for you would tick all the little empty boxes on them ones, and choose sell similar at the bottom. This will class these ones as a 1st time list again so if they don’t sell now you will be entitled to the free credit if you have to re list them next time.

Now it will get confusing and you wont know what you have or haven't listed as a sell similar so what I do is open up 2 pages of the Unsold items and the tick all the ones I want to re-list in both screens, one I will re-list and once they are done , then I will go to the other page/tab and then hit delete it will delete all them sell similar items I just re listed. It’s not a bother to much if you use the re list option because they will have that blue arrowed circle which means they have been re listed.
