harrish, You say you can't ship out, but if you use the flat rate boxes, print the labels and pay for postage on USPS.com and request pickup at your house that may be a possible way to go. You can go to USPS.com, set up an account, have boxes or padded envelopes sent right to you. The only thing else you would need is a charge or debit card to pay for it. I do this all the time and it is great. Usually I drop stuff off at the post office because I am going that way anyways.
Just something to think about if you want to offer stuff here or on other forums. Just make sure you state if you want extra for the postage or if it is included in the price.
Good luck!
