First I want to say I really am loving DC! About half my customers use it instead of paypal now.
Now, on to a little problem I have noticed though-when a customer pays using paypal their shipping address is usually already in the proper format for shipping & has been verified. However, when I ship with DC the addresses I am being provided haven't been verified or anything. I have had to correct or completely change addressess about 1/2 of the time. One customer insisted it was 100% accurate but every time I tried to input the info into paypal to create a label it was flagged, saying there was a problem with it. I had to completely change the address!
It is getting a little frustrating to have to play detective just to figure out what my customer's addresses really are! I shift info around, go to USPS .com to input the address to get a standardized one, etc. My last one today took me 15 minutes of back & forth between USPS & Paypal, erasing this, adding this, looking up that. Is there anyway Etsy shipping addresses can be verified like Paypal does? It would really make it a LOT easier!
