Wow. Who the heck does something like this, cherry picking blind bags? That’s taking all the fun out of getting one! The person who did this has a special place in the pony underworld, I can tell you that.
I mean, that's what everyone did with the regular blindbags that had codes, just look up the codes and grab the ones you want, avoid ones you don't want or doubles.
Now repackaging them after opening them, and returning them, that's scummy. Especially if you don't even do it correctly like whoever did this seemed to do, judging by the photo...
Yeah it would be one thing to close it back up and return it if it is one you didn't want but this person just took the pieces they wanted and replaced them with random pieces.
