Had to replenish my Ilford Rapidfixer and found this shop hear metro stop Anvers or Cadet in the 9th Arrondisement. They seem to carry quite a wide range of stuff, surely the digital stuff, plenty of paper for inkjet printing and for photo developing, and most importantly for me B&W chemicals. Prices are usually displayed without tax and its added at the end. They do delivery as well but its 10Euro per delivery so for my volume its too large a proportion of the final cost. Did see some developing kits there as well, like the tanks, spare reels, trays, and accessories. They're not dirt cheap enough for me to buy on impulse, but nice to know its there if I need it by emergency. Finally bought a bottle of Rapid Fixer and HC110 from them. Enough to last me for years.
