Sometimes it can be hard to get a super clear photo of the creed, or the seller may have already taken photos of the bag and put the item into storage and/or an inaccesible place. That said, I think sellers should be happy to accomodate anyone who wants additional photos or specifications about ANYTHING on ANY item. It may take a couple days, but they can get it..
It's all about the customer. They could send you a private email if they don't want their photos stolen.. or images are EASILY watermarked.
I'm as much a buyer as much as I am a seller, and if it takes more than a few emails, I'm out... buying gorgeous Coaches should be fun, not hard work
One of the first rules of selling: Make it EASY for your customers to feel confident buying your product. Period.
