I just tried the shipping through Etsy for the first time. I thought I read that there was a discount if done this way, same as Paypal's discount. The price was the same as USPS.com, shipped from home column. Anytime I've compared the price from Paypal to USPS, there is definitely a discount off the online price (including the DC).
It was priority, same price to the penny as listed on USPS. I was just surprised, that's all since I was just reading about it. I just signed up for direct checkout & tried the Etsy shipping. I do love that it was easy & time saving by including email notification right away. BTW, can that be turned off or skipped occasionally?
