Few things you to think about: 1. No zip code was specified in the delivery address. I had to search for it at google map 2. When the seller's website has specific fields for first name and last name, it is impossible to mention the "c/o Stowfly" extension. I suggest having some guidance on how to specify the Stowfly affiliate when customer details are specific and the is no place for free text (maybe add it to the address line?). In my case, the receiving person couldn't know that package is Stowfly affiliate and had to make some phone call to confirm that (but package delivered well at the end)
