I've never understood sellers who aren't willing to answer questions and provide pics. Makes no sense at all! Unless they're hiding something...
Though I agree with everything being said here, and I pretty much do answer all questions & take the extra pics requested, there are several occasions where I do that & don't get a thank you. I know I shouldn't expect it, but extra pics are extra effort & a thank you would be nice. I'm sure there are seasoned sellers who preempt that by just not bothering
