Good find, ordered a few books on my list (yet more filling up the house!). It states the international shipping is up to 21 days. I found before airmail from USA takes about a week, but surface mail takes from about 1-2 months.
Two sites to bookmark are www.bookfinder.com and used.addall.com -- both trawl numerous sites such as Amazon, Abebooks, Biblio, etc., and allow you see prices from multiple sellers in a single list. The likes of BetterWorld are also linked through Amazon so will be included in Bookfinder or Addall searches.
