The 'Claytons' refund. I bought a new 10T drive sprocket from ZBox last week, but the one that arrived was old and very well worn. I emailed Steve and let him know of the error a couple of days ago. The ZBox refund - he charged an additional (unauthorised) $20 to my credit-card yesterday, I discovered a short time ago. I guess he meant to put $20 in, not take it out. I just emailed him and will see what happens.
