I happened to be checking the D23 Boutique to see if any of those "temporarily sold out" pins might again be up for sale, when, what to my wondering eyes should disappear, but the links to those (and any) pins.
Late this evening, I saw a new update on the D23 Web site:
"For those D23 members who missed out on our exclusive pins the first time around, we have great news! This week Disney Shopping will be putting the 'D23' and 'Plane Crazy' pins back on sale, and next week, look for the Tinker Bell and Jiminy Cricket pins to return."
There you have it D23 fans! Look for the return of those popular pins starting later this week and into next week. There's no word on how many pins are available - so if you want them, better get them fast!
UPDATE #2: The "D23" lapel pin and the Plane Crazy pins are now on sale as of 4/23.
