This is part of what he says in an automatic e-mail:
If your question was to be put on the approved list for one of my items I apologise but the approved items are for pre-approved bidders only. If your question was regarding buying in bulk, sorry but I can only get limited numbers of stock and cannot supply wholesale.
Why have a pre-approved list when, before these last 4 items, all he was selling was E-Books for 1p
