You can do one of three things. You can see if your mom, pop, friend, or significant other will ship it for you, you can simply let your potential buyers know that shipments will be made on Saturdays only, or you can simply fill a form on usps.com to have the postal man/lady pick the package(s) up directly from your home when they come to drop the mail off. The form even allows you to leave the postal person a note. In the note you can let them know where the package(s) will be left. I.e. porch uner chair, on the side of the house, or in theyo hallway. Hope this helps:)
Yep, if you ship priority mail and buy the postage through paypal you just print out the shipping label and stick it on the package, then there is a way to make arrangements right online to have the package picked up at your doorstep. you can ship as many packages as you want, as long as one of them is priority mail. of course it they fit in your mailbox, you could just put them in there and raise the flag. You do of course need a postal scale if you are going to ship this way. you can buy nice digital postal scales on e-bay too. at the time I bought mine it was only about $20
