The payment page requires javascript to be active but gives no feedback nor warning that this is the case, it just fails silently with neither a error message nor a loading icon, nothing. That's very bad UX IMO, it caused me to have to reenter my details several times as it was not apparent what the failure was. <noscript> ain't rocket science. The search on the site is very annoying, tracking down what I want seems much more difficult than it did several years ago. Some compatibility information when choosing components would be useful too. Feedback as to which items will cause a free delivery to be removed from the order and which items will prevent a next day delivery would be useful to. One gets an "!" on the order screen, but the items could have been excluded much sooner in the selection process if it was known that they'd not be available next-day. IMO the site is just good enough, the experience is quite brittle. A good example is that one needs to constantly re-select the "sort by" option as the site resets it to "relevancy" and away from "lowest price"; silly. Another good example is the price selection, who selects a band of £10 in which to purchase computing goods - there should be a range selector. Using the site one feels like you're entering a battle to get it to spit out the items that match your selection. Compare uk.pcpartpicker.com which is a relative joy to use.
