Not sure if there is a discount on holders or not (probably not as that would make most sense from standpoint of promoting more VH product out), but, I think it would help VH if they'd let you have the VH holders and steel regardless if you opted out or not and offer no discounts. So even if you opted to send Tuuks in, they would mount the Tuuks on the skates and sent you the VH holders and Steel on the side. This way, you can put those in if you change your mind later, or sell them rinkside or whatever. My logic on this is that in a short period of time, there will be loads of random skaters with VH holders simply because people wanted to try the holders and were able to get them from Ebay or rinkside for cheap. Lots of them will love the holders and this creates a pool of future customers that will go with VH holders plus it creates stronger brand awareness. This can be pretty efficient way to take over a market share from other holders/steel manufacturers or at least make a small dent in the competitors revenues while creating VH holders culture. StepSteel will benefit from this as they will sell more steel this way.
