Toys r us near me had tons of these, and fox. After starting to collect pops, I quit collecting toys for resale. Good luck with your auction though. Maybe if yours does well, I'll grab a handful of these and that "rare" fox.
I didn't even know that they finally re-released some of these ^_^. They are still REALLY hard to find for me though. As a life-long fan of Nintendo it kind of sucks that they're so darn collectible and competitive but I guess that's half the fun in the end.
