I think you're right, I normally order from Ag or Mathers now because of the deletion of 4x5 FP4 and a couple of other lines from 7 day webshop.
Its nice that Matt at Ag will actually pick up the phone and talk to you so I think in future he'll get my business, 7 day were good for ordering a couple of rolls of film you'd rarely use like Portra 800 which Ag only list in 5 packs.
Still declining markets, mean less options I think getting behind people like Ag is the way to go.
