When I add a calendar to my cart (for example), I get Priority Mail at $7.80 and Parcel Post at $11.25. There is a $3 handling fee built in to these prices.
When I check usps.com, I get $4.80 for Priority and $4.55 for Parcel Post. So, my Priority Mail pricing is correct. But I can't figure out where the $8.25 for Parcel Post ($11.25-$3.00) is coming from.
Further, I have not yet installed the International patch, but would that really have an impact on my domestic shipping rates?
