The online shopping facilities offered by the supermarkets, ASDA and Tesco. Both sites have been designed using similar layouts, frames to separate hyperlinks etc, this ensures the users of one site will be comfortable using the other i.e. they will know what to expect. The registration processes in both sites are simple and straightforward with only a limited amount of information required from the user. It is important to note that neither site uses H1, H2 elements as recommended by W3C, therefore there is no hierarchy of heading levels which may cause confusion to users of aural browsers.

The shopping experience itself was simplified with Tesco due to the ‘express shopper' search facility which enables the user to type an entire shopping list onto a ‘notepad' and then conduct a search; it looks for the first product on the list and transfers the whole list onto the left hand bar allowing the user to then click on the links in the list to search for their items one by one. Asda provides individual searches using a product search box, which does not highlight data within it when clicked; this can result in errors when searching due to the previous search not being deleted properly.

Search results provided very different results; Tesco searches were very succinct with only a few relevant items offered as options whereas the Asda searches resulted in a multitude of choices within different departments, many of which were often inappropriate, resulting in subsequent searches having to be carried out. Both sites use tables in order that the user can choose a time and date for delivery, the Asda site is very self-explanatory and easy to understand whereas Tesco is confusing with different prices for various time and day slots with no explanation as to why. Tesco do offer an alternative website designed for users with impairments and accessibility
