I have a problem with the new USPS update. The Zen Cart update appears to be working fine, my problem is with the new USPS rules that they have set up.

Standard Post rates no longer show up for zones 1 to 4 shipping. The reason USPS did this was that Priority Mail rates are the same as Standard Post rates in zones 1 to 4, so Priority Mail rates will show up for zones 1 to 4. In zones 5 to 9 Standard Post and Priority Mail rates both show up. Zones 5 to 9 are my problem as I don't want Priority Mail rates to show up - Priority Mail rates are based on box size (if over 12x12x12) in zones 5 to 9. Most of my items are in boxes larger than 12x12x12.

Before this update, I did not offer Priority Mail shipping rates, only Standard Parcel (But would ship via Priority Mail to zones 1 to 4). But now, I don't get Standard Post rates for zones 1 to 4.

Any work around for this??
