I only order instock items from them and in all honesty that hasn't been for a while.
I understand the problems people are having, I just haven't experienced it first hand so I don't have anything to complain about.
I am a collector as well and I know how I want to be treated as a buyer. I have been a member of OTCA for a few years now and I only started planning my store recently.
I can guarantee that we will have the best customer service because everyone involved is a collector and understands how things should be handled.
