paypal is a trusted payment gateway. people ask for paypal because sending money through the mail is more than just risky its also technically illegal. they assume because your feedback is 0 ur going to take a money order, cash it and start a new account, its happened to alot on this site. paypal asks for a tracking # and calls the post office to see if the item was really shipped or not. its a free service so everyone should use it. also it pays off for you giving a shipping discount, and free tracking # so you save $ and can print your label from home and simply drop it off at the post office. if u take paypal, i will also bid :)
even though paypal likes to charge their fees. I still prefer it because of the security. If I mail cash, check or money order the person can keep it, not ship item and I would never be able to dispute a refund. If you would accept paypal I would be bidding. Paypal is kinda like an online bank/wallet.
yes about $8-$15 Depending on location for this type of item or can be put in Flat rate box with free Insurance and tracking for $15 (probably your better choice brinamiller22 to be safe)
