or buy from eBay in 28.5-29k range and also make use of eBay winter offer coupons. Samsung has increased the billing rates for retailers while keeping the mrp same, so i don't think that S2 will be available for 27k mark any more as of now.
You can head over to koovs.com and use the discount coupon XMASBAG for a discount of 2.5k (30k - 2.5k ~ 27.5k). Never bought anything from this site, hence cannot vouch for reliability.
