Figure delivery costs into your final price. If you spend a lot of money, make sure the seller will insure the item when it ships.
If you want more information like shipping times or whatever, ask by clicking the "Ask seller a question" link under the seller's profile.
Always make sure to complete your transaction on eBay (either with a bid, Buy It Now, or Best Offer). Transactions conducted outside of eBay are not covered by eBays buyer protection programs.
Never pay for your eBay item using instant cash wire transfer services like Western Union. These payment methods are unsafe when paying someone you do not know.
Know your seller
It is important to Research your seller so you feel positive and secure about every transaction.
What is the seller's Feedback rating? How many transactions have they completed? What percentage of positive responses do they have?
What do buyers say in their Feedback? Did the seller receive praise?
Most top eBay sellers operate like retail stores and even have return policies. Do they offer a money-back guarantee? What are the terms and conditions?
Buyer protection
In the possible event that a problem arises during your transaction, eBay and PayPal are there for you.
Pay safely with PayPal: PayPal enables you to pay without the seller ever seeing your bank account or credit card numbers. In fact, PayPal protects buyers 100% against unauthorized payments from their accounts. Plus, with PayPal Buyer Protection, your purchase can be covered up to $1,000.
eBay Security & Resolution Center: Visit the Security & Resolution Center to learn how to protect your account and use eBay's quick and efficient resolution tools.
Just make sure that you understand Paypal's policy of not refunding any money if the seller can prove he shipped you the item. For example, if you paid for a new pair of clubs and got a sweaty golf tshirt instead, you're out of luck!
