1. Finding auctions with multiple words
If you are searching for items that have one of multiple words, you can use the OR keyword in your search. For example, if you wanted to find all auctions that have in their title listing the words cat or dog, then you would enter (cat, dog) in the search field. This would return all ads that have either the word cat or the word dog in their listing.
2. Locating auctions with one word, but not another.
If you are looking for watches, but are not interested in Timex watches then you would use the AND NOT keywords. In the search field, you would enter: watch -timex. This would return all auctions whose listings included the word watch, but excluded the word Timex. (Note there is no space between the minus sign and the word timex).
3. Don't Fall for Spoof email supposedly from eBay or PayPal
Many emails you receive in your email account from PayPal or eBay are really fakes. If eBay sends you an email to your email address 朼nd they sometimes do, don't open it. Whenever eBay sends you an email they also send it to you're My Messages box in you're My eBay Page. Just go to you're My eBay Page where you will also see the email if it really came from eBay. You can open it there safely. If you receive an email from PayPal, don't click on any of the links. Instead just log into your PayPal account and you will see any notices on your main account page.
All genuine emails from eBay and/or PayPal will be always be addressed to you by name. If the email says Dear Member --it is a fake!
4. Be careful using a SPAM filter
Unfortunately once you start buying and selling on eBay, your email gets out there and your volume of spam increases. Eudora has a great free email program called Eudora Lite, free at eudora.com, which allows you to direct all your eBay related email into a special mailbox where you can filter it. Microsoft outlook has this feature.
There are also new services available on the Internet to filter out spam 朾ut they are not 100% reliable. They sometimes filter out legitimate messages and still let a lot of spam through. That can be a problem --you might not get legitimate emails from sellers, bidders or buyers. So get in the habit of checking your spam filter regularly.
Also be sure and use the same email address for both your PayPal and your eBay account. Using different email addresses can really confuse people you are doing business with. (However for security reasons always use a different password for your eBay and PayPal account).
5. Know what you are bidding on
Unless the item you are bidding on is clear and unambiguous, be a little careful. If an item description is not complete, or if you are buying a collectible or something used, take the time to email the seller and ask questions or for clarification. If the seller doesn't answer quickly and completely, that is a warning flag and you should be careful.
Be especially careful when bidding on high-priced items.

Using attractive item titles and investing in picturepacks, bold font listing etc also help your item end at a higher price.
