Replying to Shops jacking up the prices for mounting bindings?

So I need to remount some FKS's and all the local shops want $70-$75 to mount bindings. Last time I got some mounting done I thought it was like $30 which was about a year or two ago.

$75 to mount some bindings seems a bit ridiculous to me. Is this reasonable pricing or is there something else going on here? Seriously considering learning to mount my own bindings cause the $ saved will really add up over the years.
