They might as well sell adult toys, that way when they screw you, at least it makes sense.
Most unknowledgeable staff ever to work a camera store. (What's a neutral density filter?) Upon understanding what I was looking for they offered a Tiffen 3 step for $149; not even in the realm of reasonable.
Also in need of a stepping ring, I asked for a 72mm - 77mm. Was sold the inverse. The return attempt (next day) was an exercise in futility. All sales final. For a $15 purchase. I can completely understand a reasonable return policy for purchases of significant equipment to avoid 'rental' attempts, but $15?
I'm still sore.
