Sorry if this has been mentioned already but Australia TRU has wave 4 blind bags! I just picked up one from Garden City and got Chance A Lot, I couldn't find Twilight Sky who I'll snatch up in a heartbeat if I find him. They're using the 5---- code (see ->
http://mlpg4merch.tumblr.com/post/24157634436/g4-blind-bag-master-post). Strangely there were a few bags with what appeared to have code numbers not on the list, but maybe I misread them. There were a fair few left in the box and there were at least two other full boxes yet to be opened so if you're in Brisbane and want blind bags hit them up quick!
I only ever found a handfull of Wave 1 so Wave 4 is awesome, even if we apparently missed 2&3... it's not Wave 5 but it's something at least. New products hitting the shelves makes me eager to see what will eventually be released here.
EDIT: Hit up TRU again today and found new stock, omg yay!
The WEDDING CASTLE! [$?]
The Friendship Celebration Collection Blind Bags [$60?+]
Blind Bag Miniature Collection (all 3 sets with PLENTY of stock) [$20?+]
I didn't check prices because I either didn't want or have already bought online... but predictably they're at least twice the US price so bank accounts are gonna be hurting! In most cases it's cheaper to buy from US even with shipping costs lol!
All this new stock is making me excited for a Fashion Style re-release... Fingers crossed!
