Hello list,

I was wondering who here already had to work with USPS from within a  
Rails  
app to implement fullfilment. I was working with Fedex, implementing not  
only cost calculation but also the shipping request, void, cancel  
shipping  
etc. However, I have no experience with USPS and I don’t know how  
complete  
their SOA architecture is. If you have worked with it to some level,  
would  
you mind sharing your experiences?

Thanks,

Marcelo.
