Hello!
Congratulations Mattysmrs - so so pleased for you. Here's to an uneventful next 6 months with a beautiful bundle of joy at the end.
You pay for each FET - I think it's around 1,000 euros. Also if your fresh donor cycle fails to produce any frosties, PFC will do another fresh donor cycle but only charge you for an FET. If you get frosties out of that, it's still regarded as your first cycle.
Hope that makes sense.
