They are a stupid price, I agree. If you fancy a spot of DIY, you can create full rack blanks for around £7 each.
Have a search for Correx Corrugated Plastic Fire Retardant. It is also known as Fluted Plastic. You can get it 2mm and 4mm thick and the 4mm is about strong enough to use in a rack, although to be fair in full sheets we used the 2mm stuff by popping a number of cage nuts/screws through it to pin it down. We put a couple of 1U metal blanks behind it to stop it bowing too much. It is a tad of a cheap and cheerful approach, but when you need to blank an entire new suite, it actually serves the purpose very well for the money, so long as you don't mind getting busy with a straight edge and knife.

The problem is pressurization. Most I've seen fail and end up bending and creating gaps. Your data center may have contractual language that you are required to have blanks and maintain them adequately. I used them once. I replaced them once. With respect to cost of metal blanks. Wholeheartedly agree. That's why I designed and made my own e.g. a cost reduction of 90%.

Am I the only person on here that thinks all the current blanking solutions are very expensive for what you get? After all its just a piece of fire-proof plastic?

I'm after some of those lightweight "corrugated cardboard" (can't think of what else to call them) blanking sheets to put in racks to stop hot/cold aisle "rebreathing". Want to give these a go, but keep coming up on metal blanking plates. Anyone got a manufacturer/supplier that you're able to share? Cheers Mike
