USPS Shipping Module by MarcoB - RateV4, IntlRateV2 - Support Thread

[vintagenyc]

I have looked through this thread, I have a stright forward questions, can you advise if the USPS RateV4 Supports Priority Mail Flat Rate package (Small Med Large) rates. I may be missing it but I do not see that this is implemented???

Thanks

Ok I belive it does after reading all the interactions....good stuff

One additional question I did see some minor discussion is with regard to the transist time with flat rate, can that be displayed with the shipping options from the USPS server?
