you're probably just the messenger of this upcoming feature, but this is not important right now.
as per my comment on your thread- why can't etsy prioritize creating options for different shipping rates for different zones/locations in the U.S. instead?
for delivery time info, we are just reiterating what (USPS, UPS, FEDEX) websites already have available! it's even accessible to etsy buyers via the etsy shipping notification showing the tracking #s.
that is just a waste of hiring coders on your part.
sellers need zone rate shipping for different states !!!! (just like EBAY) and this has been requested in the "ideas" forum for a long time.
