Wow! Track of the Wolf and Dixie both have them at $2.50 each, limit of 12. Suzi at The Gunworks has English flints at $3.50 for 1/2" and 5/8", $4.00 for larger sizes. She also has sawed Arkansas for $2.25. Not cheap by any means. I think I need to start looking for chert and try my hand at making my own!

There was a feller by the name of Rich Priece (or something like that) that made Chert Flints (which I did purchase from him, but sadly I believe he has passed on... He was very well known at the American Long Rifle forum / so you may have to check over there to see if anyone continued on with making them?
Chert flints do work, but they can be "iffy" with lesser quality locks. However, I don't recall having any trouble with them when using them in the Siler and L&R Locks... IMHO, the Black English and French Flints will out shine Chert Flints by a long ways / but if it's all you can get at this time - it's probably worth the gamble. How they will perform with the "offshore" Locks, I don't know? Just food for thought Kees... At the price gouging they are charging now for flints - it would be worth wild to try Chert - or ride out the price gouging and shoot Percussion Lock Rifles... Bottom line, they are now (both ignitions) are gouging the public... Time we started to make our own Percussion Caps and Flints... Just my opinion...
