I had purchased GTA4 and EA sports Cricket game way back in Dec08 and the deal was good and smooth, have also tried intencity as they have lesser quotes compared to nextworkd but mind you its very less difference between them, even 2 days back i have preordered Mafia2 and Kane and Lynch @ nextworld.in for (Mafia2 - 470 + 40 shipping, KAL2 - 899 + 40 shipping)
= 1449 minus 12 Reward points whereas the same in intencity.in is 475+900 = 1375, so booking at intencity saves you 74 (1449-1375) but the reason i bought at nextworld was that the transaction can be done anytime just like ur mobile bill but for intencity its a net transfer and for me icici bank is on only till 6.30 pm and satrudays upto 2.30pm only and when i tried i do it i wasnt as i logged in after the time limits whereas in nextworld i placed the order at 11pm and it was quick and fast.
