Edit: Thanks to the arena I'm going to be able to get a Pinkie Pie!
I finally got to a build a bear shop (it's 1 and 1/2 hour from my house) but they were out of pinkie pie! They had lots a rainbow dash so I managed to get that one but I'd still like the pinkie pie and she's also sold out online.
I'd be willing to pay if someone's build a bear has them in stock or possibly trade for something (though my collection isn't that big) I have some g1 and g4 ponies.
I haven't done any trades here but I have good feedback on eBay (I will PM you my eBay profile)
BTW build a bear employees said twilight sparkle is coming in the fall
