Stopped by my local Walgreens for the heck of it and happened to find what was probably a full box of Wave 5 blind bags (the yellow ones) They were $3.29 each, but... BUT I found number 19 in there which means PRINCESS CELESTIA! For less than half what I'd have to pay on ebay! I picked up Breezie too because I really wanted her. May have to go back and hunt for the other two princesses and Lyra Heartstrings.
It's awkward enough going through and checking all the numbers on the bags, but this time they were up by the cashiers and it just so happened that the cashier directly accross from the ponies was an acquaintance of mine from school.
