The prediction of a dramatic increase in online grocery shopping over the next five years is only likely to be fulfilled if online supermarkets present a more efficient and logical shopping experience. Therefore, usability testing is playing an increasingly important role in the development of e-commerce websites. To date, e- commerce usability research has only focused on the ordering of singular items and the issue of multiple item ordering has not been researched. This study aims to start to fill this gap in usability research. Based on the results gathered, a set of ten usability criteria were established, with a focus on the ordering systems for sites selling multiple items and quantities
