Wireless mic's cost less for us because it takes fewer and requires
zero installation resources. Wireless speakers are on the want list
and wireless mixing board is on the dreaming list.

They probably have kept all old invoices and are looking at what
they paid for their 700 MHz wireless mike 20 years ago.
But that does not mean the cost for a replacement will be the same today.
It may well be 1/10th of that amount.
