What better way to maximise footfall to your store than to set-up shop inside places people visit daily for tomorrow's bread and milk? Undoubtedly that's the thinking behind Argos' new batch of "digital stores," where tablets replace order slips and pocketable pens to replicate an online shopping experience, now popping up within various Sainsbury's locations. The surprising tie-up was announced in January, but today sees the first Argos digital stores opening at Sainsbury's supermarkets in North Cheam, Surrey and Nantwich, Chesire. These smaller-than-normal outlets will offer up to 20,000 items for instant purchase or later collection, with everything else in the catalogue available for home delivery. A further eight locations will also open their doors at some point this summer. It's yet another one of Argos' modernisation schemes that include its partnership with eBay, click-and-collect stores and online 3D-printed jewelry service. And as far as this particular alliance with Sainsbury's is concerned, Argos might well be getting the sweeter end of the deal.
