Cheaper to sell fewer lots, and more likely to be bid up by the serious buyers, buying them for individual resale or for a school/workplace/etc.
Which is better:
- 8 lots selling between $50 ~ $100 each, postage and packing for each (maybe paid by the buyer, but there's still expense for the auctioneers.) Any returns/failure to pay, chance is magnified when dealing with private buyers
- 1 lot selling between $300 ~ $600, OK it sold for less but the auctionhouse can sell more items that week and take more commission, plus they have less chance of returns or failure to pay when selling to a company.
