I have to say it isn't that simple.
When Alta and I were in Ottawa, we found a store that stocks "our sort of stuff" - and almost everything she had was DV and things like fairy statuettes and that. We talked to her about it - as we had read up on the store and it had sounded great, and we'd actually hoped to buy stuff - and she said yes, she USED to stock all the good stuff and the books we might buy and so on - but she needed to survive financially - and the stuff that sells is - DV and "product". By which she meant the statuettes, pretty cloths, pendants with little plastic angels and so on.
She was determinedly hanging on to a few goodies - there was a Waite and two LoS decks, as I recall - but PILES of DV. And she orders all the stock herself and knows her stuff - I think she was pleased to be able to talk to people who took it seriously. But she has to make a living.
Same thing with
the one in the small town near where I live - though they do manage to have a lot that ISN'T DV - mostly because they are both practising witches as well, and run circles that people pay for on the side, as well as healing, ionising (I just had a look at their website, which is NOT up to date (I was there not long ago, and that is NOT their current stock...).
