I have about 7 pairs of XMetals that needs the flex couplers replaced, mostly Juliet’s, a Penny and a Romeo 2. Here’s my questions, is it better to send 1 pair at a time to someone or send them all at once? Also, do you think it’s possible that I could get a slight discount if I send them all to someone? I used to do the tune ups myself, but I can’t anymore due to physical reasons. I just wanted some feedback. Thank you!
