I don't doubt you already caught the news earlier this month that Dell would be selling XPS gaming systems via HMV's Gamerbase in London. At the time it seemed like a one off arrangement but it turns out that assumption was a little premature because we now know it was the precursor to Dell and Tesco striking a deal to see the former's PCs sold throughout the latter's UK store chain.
Some, of course, may see this as yet more evidence that Dell's direct sale policy is loosing its potency. Certainly most consumers that Dell will be targeting through Tesco probably aren't the kind to care about a company's sales policy, especially not over arguably more important factors such as price and value for money. As long as offline pricing isn't too far out of kilter Dell should even be able to compete with other well known supermarket PC makers, such as Medion.
A variety of XPS and Inspiron systems will be available, although no specific details are available yet so whether or not the choice of system will vary by store is unknown, but we suspect likely. With Tesco pulling around 13 million customers a week into its UK shops it can't be denied that Dell should get its products the exposure it doubtless wants and those customers unwilling to part with their cash without checking out their prospective purchases first will be pleased too. After all, if you'll forgive the obvious pun, every little helps.
