As far as I know these are the sites that are currently featuring some deals:
These are the others that I have no idea if they're under renovation, maintenance, or just closed
Here are some of the newest group buying sites that are to offer some great deals soon:
From all the new ones, I'm going to keep a close eye on Pakyaw.com.ph. It has one awesome launching promo! They're actually giving away an Ipad, Nintendo Wii, Macbook, and a Flat Screen TV! If they're giving away those kinds of prizes, I bet they're going to feature some awesome deals! The first deal goes live on February 1! Gonna mark my calendar for that day!
