Disney Store.com is selling all of those items for way more than they are sold elsewhere, just fyi.
The Mr. Potato Head is the very same as I got at Toys'R'Us for $50, which I still think is a rip off.
Jessie will also be $50 since Buzz and Woody were as well.
As for Lotso... I was going to guess he was $50 too but maybe not? If he's that much bigger maybe, but certainly shouldn't be as complicated as Buzz Lightyear.
p.s. I heard that the aliens are sold individually as a Target excusive for $9.99 each. So if you wanted more than 3 but didn't want to commit to another 3pack, this is the way to do it.
