If you don’t want to track a lot of daily deal sites, there are already lots of aggregators. DealWatch is another contender, offering summaries of deals from five major providers and across 14 cities.
You can sort the deals by location, price and newness, filter out particular categories (no more facials!) and optionally sign up for a daily email summarising them. Given the number of options out there, DealWatch doesn’t seem particularly comprehensive, but I’ll be surprised if it’s the last attempt we see in this space.
