Well... An option you have would be to join the Palisades Collector's Club. That way, when Super Grover is made available a few days after the conventions you'd be E-mailed the notice and could buy him there. Oh yeah, if you notice, they accept payments for newly signing-up members via MO as well. Would contact Tony at
TEqui@PalisadesToys.com and let him know what you're talking about if you are in search of more help with joining the club. Other than that, you might get some existing club member to do you the favor of buying extras.
Hope this helps and have a good day.
