When users add photos to their basket on iStockPhoto, they have to be careful as largest (and most expensive) option is set as the default, and this is not strongly emphasised. The result here is that a small but notable percentage of users will buy the most expensive item without realising. The honest approach would be to avoid any default altogether, so the user has to make an explicit choice as to which size they wish to purchase.
