We purchased the toilet bowls and almost all of our mixers/taps/showers from them.
We didn't really compare around for the price, but we felt that their pricing is quite ok.
If you buy a lot from them, you can try to lower the total bill sum.
I found their service quite good. We had a problem with the kitchen tap we bought, it was leaking when installed. Brought it back to the store, they checked, and exchanged a new one for us.
