a bit late,
still no changes... The shop at Rocca Al Mare has relocated inside the mall to a bigger place, and the shop at Punane is still there, moved one slot further back.
Actually, the 1:100 Zvezda kits are on average about 25% cheaper than in the Netherlands. Not sure about the other kits though ( reference: a 1:100 T-35 is 6 euro in Tallinn, and 8,5 euro in Arnhem, the Netherlands, any other set costs 3 euro's vs 4 euro's )
For 28mm scale, there is gamersguild at Kentmanni 18 in Tallinn, Owner is a UK guy
