Try the mobile phone before you buy it - in Noida

Dubai-based Jumbo Group has opened its store in The Great India Place, Noida.
Here one can try out mobile phones before buying them. I.e. live demo as opposed
to the dummies placed in other retail chains(Subhiksha etc.). But the prices
are slightly higher here. (See source)
So a good strategy would be to try out and zoom in at your phone at Jumbo, at
the Great India Place and then go to the basement of CenterStage Mall and buy
from Subhiksha or The Mobile Store(located side by side).
