Need a Shipping Label / Postage Solution

[Hammerhead]

Can someone suggest a Joomla component that will print shipping/postage labels for daily orders via USPS?  We need a way to easily get an invoice/packing slip and an address/postage label printed based on quantity based shipping prices.

I've seen Virtuemart Manager (link below) but was hoping for a few suggestions for other alternatives to see if there might be something even easier to use.

Thanks in advance!

I use and absolutely love ShipWorks.  It is not a Joomla! component so you may not be interested.  It is a program that installs on your local computer.  You then upload a php file to the root of your site that allows ShipWorks to communicate with your site.  It can be set to check for new orders at the interval you choose and can be set so that once a new order is downloaded it will automatically print out a packing slip or invoice.  Then, when you are ready to ship, simply choose that order and click ship.  Choose your shipping options and click one button.  It will print out the label (great if you have a thermal label printer) and then go to your site and change the order status to shipped (or whatever you have it set to change to).  It then also automatically sends an e-mail to the customer that you set up that can include the tracking number as a link.  It has been a life saver for my business and has allowed me to really grow.  Our average turn around time on orders is less than 1 hour form the time the order is received to when it is shipped and the e-mail with tracking info is sent to the customer.  It is subscription based so that may be a deal killer for you.  I was hesitant to get started with it at first due to the monthly fee but they do have a 1 month free trial.  I used it for 2 weeks and was completely hooked.  I could not be nearly as efficient as we are today without it and it more than pays for itself each month in improved productivity.

And no, I am not affiliated with them in any way.  Just a very happy customer.
