If you are buying by way of a web-based seller, you shouldn't give up more details other than you need to.  Simply provide the important details to complete the sale. Compared with bricks-and-mortar stores where you will need to have a large number of stores to cater to several places, you just need one with an online store. Many of the merchandise you find here in our website are straightly hyperlinked to ebay.  If you click on them, you are going to be sent directly to the very product on ebay. Avoid putting in a bid on items when vendors can not provide you with a straight and convincing reply when asked about something about the item they're offering.
