Checked the LBS and no Frog cleats there (4 different locations, no dice)but they did rummage up a NIB Syzr pedal set which obviously they will have to eat as it is unsellable w/o replacement cleats.
I hope they don't have to take a loss on those and I see some people are trying to sell NOS or even junky, used old Speedplay pedals and cleats for 2-3 times the price of the retail when they were available. Not sure anyone is getting those prices but plenty are trying and the LBS has a good chance of at minimum getting back what they paid for them on Ebay or other sites.
