Cool :-)
Im in Dublin, you wont find a lot here sadly, Ive never come across blind bags..the best place for g4 ponies is Toymaster in Dublin city centre, they have tonnes, Im always in there! Smyths is the main toy store here but dont bother, all they stock is the main 6 or whatever the bronies call them nowadays...lol
charity shops are hit an miss, I rarely get lucky..
Feel free to PM me if you need any help navigating your way around ;-)
