Small updates to existing PHP shipping calculator

In Progress

Our website has an existing shipping calculator:

[url removed, login to view]

I would like 2 small changes made to the page:

1. All domestic orders under 1 lb currently only have the $[url removed, login to view] flat rate option, but sometimes buyers want priority mail. Domestic orders under 1 lb should list both the flat rate AND a priority mail option that is calculated based on the Priority Mail 1 lb rate. Calculation of the shipping cost using the 1 lb rate should use an existing function and not require any new coding.

2. Foreign buyers usually have their site settings configured to display weight in grams (as opposed to oz/lb). An additional weight option should be added to allow weights to be entered in grams (display of up to 6 digits). The code should convert this weight into oz/lbs and then use the existing functions to get/display the shipping costs. The final page displayed should look identical regardless of whether grams or oz/lbs are provided as inputs. Some error checking should be included to disallow entering both grams and oz/lbs.

I do not anticipate that these changes will require more than 1-2 hrs of effort.
