One of my favorite shops, Still Plays with Dolls, has an amazing deal right now on resin Whisper and resin Secret ball-jointed dolls (both MSD-sized dolls by Goodreau). These girls retail for $310, and they are on sale for $155.
In addition, when you spend $100 or more (yearly) at Still Plays, you can join the Player's Club, which entitles you to special club pricing on their items, even on your first order. This is a fantastic deal--you get access to tons of great items (including Monique Gold wigs for $15). They have a great selection of items and great prices (and did I mention their service is great, too?). Check out this link for the details.
