Which are the recommended multi brand home appliance store in TVM

We are in the midst of home planning and would soon need to buy appliances like washing machine, TV, dishwasher, refrigerator etc. I stay closer to Attingal and visited a couple this side like Nandilath and found their choices very limited. No new products like Samsung bespoke range or Bosch latest dishwasher models. Before I decide to go online for purchase, I would prefer if there are better offline showrooms where I can get the touch and feel of the products. Appreciate any guidance!
