carrefour also carries detergent, rinsing agent and salt. even carrefour own brand (its good btw)

yes bosch is pretty great. siemens too - i believe it's essentially the same product under the hood. basically all the european brands gave me good experience and yes not a hassle to get the detergent and stuff (anymore). it used to be harder but they are getting more and more widely available. sadly the price still is high.
