He didn't rip you off, he was straightforward and answered your questions, you couldn't agree on the terms, and you cancelled the transaction. Does that merit you coming on here and badmouthing him? What are you warning people about, that they will waste a few minutes of time and be annoyed? There are so many actually shady record dealers who overgrade, lie, etc. (many on here), I don't think your post was merited.
For the record, he's a conservative grader, and he deals in rock / garage a lot more than soul, I don't know if that influences his shipping policy.
EDIT: and I don't particularly know him well or buy from him a lot either, I would do the same for any random dealer you made the same complaint about.
