Even Croma is gone now. As is MMT, Bigbasket, Yatra, Tanishq. All the options seem pretty useless to me now. Most of the vouchers are for apparel and other luxury things (mostly apparel). I mean, most people having Ultimate are heavy spenders. How much clothes will you buy for, say, Rs.40000 (40000 points)?
A saving grace is Taj and Marriott. But then again, there are better ways to get hotel stays. Apple Imagine seems to be the only worthwhile option anymore.
