[quote name='J7.']First Class Mail on anything under 13 ounces with delivery confirmation paid through Paypal. Bubble mailers bought on Ebay or on Amazon using credit. I bought 250 bubble mailers for $33.40 on Amazon using credit. I've seen 125 bubble mailers go for as cheap as $11.XX on Ebay, others ranged from $13-$18 for 125. 6''x10'' (referred to as #0) is the size you want.[/QUOTE]
Yup this. I mail a game out for about $2.09-$2.43 (depending on weight) first class with delivery confirmation with Paypal shipping. I bought 100 bubble mailers for $19 shipped on Amazon. Then you can just drop off in a mailbox anywhere, no need to stand in line at the post office.
For bigger or heavier stuff, buy boxes (not at the post office, they are way overpriced, try Wal Mart) that will fit your item and pack it up yourself. Don't use the flat rate boxes. Generally it's cheaper using your own box. I mailed 3 games out in a box priority mail and it was only $4.90 with delivery confirmation using paypal shipping. If you don't have a scale at home, just go weigh it at the post office, most have a self service kiosk you can use to mail stuff, but you can also just weigh stuff without waiting in a line. Then go home and buy the postage with Paypal. Delivery confirmation is free with priority mail or .19 with first class as opposed to .80 at the post office. If you are shipping a lot of stuff, just buy a scale. I got one for only $13 and it makes life so much easier.
