I have a site that has been working fine for 5 years. Recently the shipping module started to act up. When you select standard post and go to the payment section, the selection is changed to Express (most expansive option) and there does not seem to be any way to change it back.
This is on a 1.3.7.1 install (for a variety of issues including how he wants to process credit cards)
I have uninstalled USPS module and downloaded USPS V15 Rate v3 B. (I understand that this module works with older versions)
I then re-installed USPS mod from Admin Control panel.
Although I cannot replicate the issue any more when I do a test order, several people a day write to say that they did not place an order due to the problem with the postage and orders have dropped from 50 plus a month to only a handful. We added ups but their rates seem quite high.
Any suggestions as the site is losing orders daily. www.doma-italian-market.com
