This one is so good fr I read it at a friend's. As someone living in europe, ebay/leboncoin/vinted/etc. are really good to find 4th, as for dices and minis, there are sellers who give discounts for "bulk" purchases. Need to be extra careful tho about package (if it's light, it's probably a scam).

I've yet to search much on eBay, one of the stores in Sweden has had a decent influx of used copies so far. But others seemed to get the same idea so might have to branch out.
