just go to their website..
safe and secured ang paypal, and the fact na under sya ng ebay, so possible na pwede kang maghabol. you can just register your credit card number and they will give you an account. so all your transactions will be logged thru that 'account'. ingat lang sa mga fakes na kumakalat sa ebay (international). if you plan to sell your items, better na mag-pondo ka to 'up' your reputation (based on transactions and positive feedbacks from sellers). Usually, the first step (when buying) is to check the seller's reputation score and check their buying/selling history. please take note of how many negative and neutral feedback the seller got as well as bid retractions (and also, naka-indicate naman sa ebay kung the seller have [recently] changed his/her id.

haba na ba? hehehehe.. just trying to help you out. lintek yang ebay na yan.. nauubos pera ko dyan! hahahaha.
