So I recently came back from Singapore after a ten day trip for a school event (Fluttershy yay!) and whilst at the Changi Airport waiting for my flight back home I decided to check out a toy store in the airport.
The store had a limited supply of ponies but they did have the Fun at the Fair (Apple Bloom and Sweetie Belle) and Camping Trip (Rainbow Dash) sets for $23.27.
Sadly I only had about $12 Singapore dollars left and they wouldn't fit in my carry-on luggage but they were there, so they may spread around soon enough (I didn't check any other toy stores in Singapore so they may have already)
