Sellers should always display full shipping addresses to the shopper. A small omitted piece of information in a shipping address can mean the difference between a successful delivery and a return to sender. I love Monoprice.com, where I buy my electronic cables. They have a wonderful ultra slim HDMI cable that I purchased recently. However, they could stand to follow my advice and always show all shipping address information. In the first part of the Shipping step of checkout (Image 1), they have you enter a Shipping Address and they show you all of the information that you enter in. In the second part of the Shipping step of checkout (Image 2), they show you the address you selected and you choose a shipping method -- however, they do not show you the entire address (note the missing #950). The question that arises is whether the shipping address on the actual package will look like what was entered in Image 1 or what is displayed in Image 2. And that difference could mean a return to sender and an unsuccessful delivery.
Frustrated Shopper Suggestion
All details of a shipping address should be displayed during the checkout process so that the shopper can help verify that the address is correct and that it has the maximum chance to make it to the right place.
That's all for now. Gotta go shopping!
