I also doubt how many of those they can sell. People need it often are more likely going with truck brands. Few of the normal DIY crowd would shed big money to get a complete set of these. The only time I needed crowfoot was when doing valve adjustment, because I insist on torquing everything to factory specs. I just got the one specific size from Snap On, simply no need for a comprehensive set.
Based on Tekton's rebranding prices, I doubt the price would be super competitive. For example, the same strike cap made in USA, Wilde pry bar set: Menards $25, Tekton $36. Frankly, whatever Tekton sells, there seems always something similar or better at a better price.
