Check out Bidbud where you can add a limiter to prevent bidders under a certain feedback % (that you choose) from bidding on your auctions. Sorts the wheat from the chaff quite nicely.

Cheers. This is what shows on the TM sold page (I generally do everything from BB). Do you reckon the "," could be causing the problem in those fields?  Selected Shipping Md NZ Wide PTP Courier Bag Tracked No Rural Delivery Address , ,  Delivery Instructions Please leave in front porch if not at home. Thank you  

I only ever use PTP couriers. Only 3 sizes to choose from with a max of 25kg on each, no calculating volumetric etc. Small bag will often take 2 books at $6.45 nz wide and $5.30 local bag included. I just sort bag size when listing so no surprises. All repeat info is saved on site and TM is integrated so it takes about 3 clicks start to finish. :)
