PayPal USPS fees incorrect?

[sunspekkies]

Has anyone run across this yet?  I'm shipping many identical packages, always 1.9 oz. and in flat envelopes.  When I choose to go to the post office and pay for shipping (First Class) at the kiosk, they're normally $1.09.  When I ship them from my PayPal account, they range (depending on shipping address) up to $1.58 including the delivery confirmation.  This roughly $0.50 is a huge problem because I'm shipping several daily.

What am I missing?  Why is there such a difference?  It's making me want to do all my work at the post office.  If it was just once or twice - no big deal.  But 10+ times per day is getting expensive.

Same thing happened with me just yesterday. PayPal shipping was 1.85.....went to PO as I knew this couldn't be.....and it  was $1.05.

Anyone else having the situation where you enter the package information, pay for and print your label, ship it out, think it's all fine then a few days later get a note/email from your buyer saying they had to go to the post office and pay additional money to pick up their package?  What the heck is going on!  One package was a shirt in a legal size envelope and all told paypal/usps charged almost $10 for economy shipping!!!!!!!!!
