How I do it:
During the week I search Ebay Pulse to see what is the hottest things selling at the moment. This is free, and it will tell you what people are searching for.
Saturday Mornings is spent out at Yardsales, or thrift stores getting things to sell. Once I get the items that I will have to sell for the week, I spend the next few hours taking pictures and writing descriptions about it. The better the photos, and the more descriptive you can make the item, the more money you will get for that item.
Once I have the photos and the descriptions I am ready to post. To make really professional looking Ebay Listings I use the free site Auctiva. If you are wondering why, I think this photo from their site says it all.

With this program you can schedule your listings to start when you want to, and use more photos for free than Ebay will give you. There are over 1500 FREE templates that you can choose from giving you many options. You can also save your shipping details and auction details and reuse it many times over. You simply can not get a better deal than this.
So once you have your auction listed you sit back and wait. I try to make mine last a week, starting and ending on Monday nights. Since over the weekend many people aren't online. It seems that Monday is the best day to start and end an auction. Most people get on Ebay on Monday's and Tuesdays at work. I find that ending the auction at nights between 7-9pm EST is the best and you get the best prices for your items. With Auctiva you can schedule it to end any time you want. Which is why I highly recommend this site. You do everything online and nothing to download.
After you make your sales all you have to do is pack and ship. Only do this after you collect the money. Most people will want to pay with PayPal. This is free to sign up with. This by far is the easiest way to collect money for your auctions, and the quickest. But you can also have them send you money orders through the mail. This way may cost you a few sales.
The thing that you want to know about ebayer's is that they expect their packages shipped the next day after they pay for the item. If you don't want to go to the post office daily, then you simply put in your listing, shipping will only be done on this day and this day. Now you won't have to go to the post office daily and you won't get emails from people asking where their packages are.
Ebay Dropshippers
Another way that you can make money on Ebay is to dropship. This is where you list the items, and then send the list to the company and they do all the shipping, packing and you just sit back and collect the money. The downfall to this is you must have a reliable dropshipper. Without the reliable drop shipper you will be out in the cold. You are depending on them to ship the products on time so you can make your money.
Finding a reliable drop shipper can be done. One program that I use is Salehoo. they will walk your through step by step to make the most money using dropshippers. They have prescreened many drop shippers and suppliers to give you the list of the best and most reliable. With this you can find suppliers for DVD's, Clothing, electronics, televisions, and many other suppliers for your products.
You will make more than $100 following this program layout. Try it today to start making your money. The small investment you make with this program will be paid back to you many times over.
Build a Niche Store
The last way to make money with Ebay is Build a Niche Store. This is the easiest way to make money with Ebay.
What it is:
Buy the software and you instantly have access to refer people to ebay's many items for sale. You don't actually sell , pack or ship anything but send traffic to ebay. You then make a percentage of the sale.
Money spent:
You will need to buy Build a Niche Store.
A website
Webhosting
The program will walk you through the rest. For less than a hundred dollars you can get started with websites that are premade and ready to do nothing but earn you money. You can set up several sites a month each one on a different topic and then sit back and watch the money roll in.
The search Engines will find the sites and index them quickly this is the nicest thing about Build a Niche store, ebay listings will automatically update and your websites will be constatly changing with the newest up to date listings from ebay.
You build each store once, than you are done with it.
Some simple math:
If each of your websites bring you in $100.00 a month in commissions and you have 10 of them you can easily earn $1000 a month by doing nothing else. Multiply that by several more sites and you can see how you can quickly earn. This all starts out with just a small investment.
This is one investment that you don't want to miss out on.
