I am having an issue i am sure is EASY to fix... but im drained so its not coming to me.....

On my website there is an estimate shipping button (which i love but dont need if its too much trouble)

Anyways... i get the table rate and UPS on there..
what i really want is estimated USPS and UPS to match my estimated USPS and UPS on paypal (which is how i accept payments)

on zen cart i am having trouble getting my UPS to work with me (i cant get it to change rates correctly so in the end it comes out cheaper than USPS!)

and i have not been able to set up my USPS correctly on zencart for some reason.

how do i make them all match and work corectly?
