You may have noticed the discounted USPS postage rates on PayPal after selling an item on eBay. Wouldn’t it be nice to get that same discount for all of your shipping?
Using the link below, you can ship anything via USPS, including 1st class mail (with the PayPal Discount!). Note, you will need to be logged into PayPal before clicking the link.

I wrote this post several years ago and there are now other alternatives as well. The best in my opinion other than PayPal is PirateShip. I have used them a ton in the last year. Great pricing and it’s a free service. You only pay for the shipping charges. If you are an eBay seller, you can directly import your sales for shipping.
