My reaction is that it is just one more gimmick and I never bothered. It was originally represented as a way to identify experienced, professional shoppers but I suspect more newbies than pros registered. The industry would love to have some way of identifying shoppers who are professional in handling and reporting shop and won't flake, but with no criteria for their certifications except ponying up money and no criteria for IC Pro except providing your personal info to an outfit that in and of itself can offer you no work, they have been pretty unsuccessful at having a marketable tool to identify 'good shoppers'.
