The best way to go here is to contact UPS (at UPS.com) and set up a "Daily Pickup" Shipping Account with them. When you do that, they will supply you with FREE "UPS Worldship" software for your computer. That software actually connects to UPS over the Internet, and calculates your shipping costs for each item you send. You can ship by UPS Ground, Air, Overnight, any way your customer wants to pay for. It also keeps a record of your shipments, your Tracking Numbers, and much more. It prints all your official UPS Shipping Labels, too, so that all you have to do is slap that label on your package, and you're done! UPS will "rent" you a Shipping Label Printer for only about $4 a month, and provide you with all the FREE shipping labels and other supplies you need for that printer. Setting up a UPS account is cheap, and it really saves you a great deal of hassle.
