<p>I live in the united states. what places can I get the cheapest IB study guide books? I already checked amazon, half.com and ebay but they are still not that cheap. I need specifically the biology one, english, and history books.</p>
<p>There are few, if any, stores that sell IB prep books. Your best bet is amazon (UK amazon has more selections than the US one), <a href="http://www.ibbookshop.co.uk%5B/url%5D">www.ibbookshop.co.uk</a>, or <a href="http://www.oup.com/oxed/international/ibdiploma/%5B/url%5D">http://www.oup.com/oxed/international/ibdiploma/</a>.</p>
<p>Some of the UK Amazon sellers have cheap books, but most do not ship internationally.</p>
