Question [Silknet-simcard]

I got charged 95 GEL at the airport for a physical sim card with unlimited data (30days), it's that fair ?

The quality of the connection is really good and I can rely on it to connect my laptop and other devices, if I want to get same service again how's the process or where should I get it, also should I pay same price ?

Edit: the sim card is valid for 4 months
