I have received several NETeller payments from Poker.com in amounts less than $10.
I once received a NETeller payment from Allstar Affiliates in the amount of $15.00.
I once received a NETeller payment from Casino Blasters in the amount of $12.78.
Of course you need a higher minimum to send checks, wire transfers, etc. But for NETeller payments, a $250 minimum is way above the industry average.
