I've mostly used 7dayshop for film supplies, and the unhurried speed of delivery, given the free rate, has never been a problem for me, since I'm generally only replenishing freezer stocks anyway, and order in good time. I've never used Silverprint yet, or Ag, but have heard only good things on all the photo forums I mess around in. I've had a browse through Ag, and been surprised to find that, even with postage charges, many of my favourite films are working out less per roll than 7dayshop, so I'm planning my next order to go to Ag, greatly encouraged by the good reports here.
