At the Shoreline, WA Costco we just found bundles with 4 DP - MD boosters and a 4 pocket portfolio. Price was $15.97 (basically the retail price of 4 boosters - so "free" portfolio). They are appeared to all include a GE and MD booster and 2 of the 3 earlier sets. Kinda cool to find these at Costco. Not sure if this is local only. YMMV.
