I added the individual parts for a 500mm C-Beam linear actuator and it came out to about $169. The same linear actuator kit is about $149. Assuming I added the parts correctly, it appears that ordering a kit/bundle is actually more economical than ordering the parts individually (seems logical). For those kits/bundles where that is true, please add something like "Saves 10%" to the kit/bundle description to help customers make more informed buying decisions.
