Can you post something about the ones you frequent in Western MA? I get out that way sometimes, and actually am going to visit a brewery there this weekend.
I've not been to Awentree in Easthampton, but I'm told they are great. There are also shops in Shelburne and Greenfield. I haven't been to either in a long time, but I don't recall a big tarot selection.
Northampton is where the tarot stuff is at. In the village of Florence, there is Groundings, which has a huge tarot card selection, and some Lenormand. Friendly.
In Northampton proper, there is Inspirit Crystals, which has some tarot books and a revolving kiosk or whatever you call it of tarot and oracle cards. Pretty good selection -- only place in town selling the Madenie Tdm if that's any guide, but they lose points from me for wasting limited shelf space with a ton of Doreen Virtue decks. Sorry, that's my bias: I just think there are other decks that could be hitting the market instead of yet another angel deck.
Where I've gone most often to buy decks is the Mercantile, which has stores in Northampton and Amherst. Not a metaphysical shop, more a purveyor of odd imports and funky stuff that tourists and college kids get. Kind of like a head shop without the drug paraphernalia if you get me. But they have a case of tarot cards, standard LoS and USG titles, in an amount that rivals the metaphysical shops. I go there because they frequently have sales. I've almost never purchased a deck full price because of them. I'm talking 25-40 percent off sometimes. They have put big coupons in the local free weekly paper the Advocate too.
Those are the ones I frequent.
If I had limited time visiting from out of town, I would do Groundings. The order of preference after that depends on if you are just going for tarot, or other stuff.
