It looks like the USPS Shipping Assistant is down (has been down since yesterday). I am hoping it will be fixed soon. In the meantime, has anyone used the PayPal mailing? It looks like you have to pay for the package through PayPal, but does it give a discount for delivery confirmation? Through the post office, delivery confirmation is typically $0.75. Through the USPS Shipping Assistant program, it drops to $0.19 (a fairly good savings if you have multiple packages to mail). Does the PayPal mailing assistant give the same discount so that delivery confirmation is only 19-cents? Thanks!
