Dealzza has got a very neat UI, but takes quite a while to load. They provide many options to filter deals based on discount %, categories, source (deal sites), price and time. The content is aggregated from just 5 daily deal sites (they claim 9 though!) with the top two – SnapDeal and Deals & You missing – and with over 40 such sites out there, we expect more from an aggregator.
Further more, what is really required from a deal aggregator is to show only the top deals with an additional option to view all the deals. Blindly aggregating deal from all the group buying sites doesn’t serve the purpose! Dealzza might need to work on getting the basics right.
