Klingbeil charged me like $20 for Flex Notches in my boots and this was before they sold out, so they've been charging for some extras on stock boots for a while. I think tongue lace bars were free, though every time I asked for them they never put them in and instead wanted me to send the skates in later to get them put on for free, which basically made them cost something like 60+ bucks because you have to pay shipping both ways.
My personal favorite is if you lose your insoles (the cheap piece of leather) they charge you something like $40 for a replacement pair. I almost asphyxiated when they told me this (over the phone) and ran to the skate tech and bought some cheap Reidell insoles for $13.
