AirwaySim's Credit prices have been slightly updated today. Our previous price check was made in December 2015, and today we're making small (~2-3%) adjustments to the prices due to changes in our payment system costs. The price of the 'standard' 10 Cr pack is 5.5 eur, and remember that even up 20% discount is available when making a larger purchase.
If you have not subscribed to our e-mail newsletter you'd probably also like to know of our discount code for the next two weeks:
"The JULY19 discount code gives you a 10% discount from the total price of your next AirwaySim Credits purchase. This code is valid until July 14th 23.59 UTC."
