The two shops i visited were located on the GT Road called Fancy Emporium and Chabra Emporium.
Some of the other shops are as follows..
Dadoos Ceramic Group-7895506593
Crockery Mart – 9152307189
Nawal Ceramics -9152612610
Bright Crockery India- 9368689332
Chuni Lal and Sons- 8899224433
Kalka in Haryana, near Chandigarh too has couple of shops selling Khurja stuff, though the prices are relatively much higher and lesser variety. If you are around, do go have a look. The shops closest to the temple on the right hand side have the best stuff available.
