If I'm not mistaken Loomis is now owned by Shimano and I don't think they sell blanks...if that is how you're trying to save money?
Have you tried your local shops and no one carries them in your area?
Our local shop carries NRXs but I live in London ON so shipping would obviously be expensive.
Not sure how often they go on sale at stores but I suggest you keep your eyes on the classified section, they do pop up now and then.
