Ocado set for price war with Tesco However, Mr Steiner, one of the company's co-founders, is believed to be set to tap into the growing trend of customers searching for grocery bargains online. As a second flank, he is also expected to use the company's results to demonstrate its decreasing reliance on Waitrose - its original supermarket partner. A number of analysts have pinpointed Ocado's reliance on Waitrose as a reason not to support the shares historically. At flotation, as much as 75pc of items sold came from the John Lewis Partnership-owned grocer. But Tuesday's presentation is likely to focus on that number having decreased to 40pc of total sales, with just 20pc of Ocado's range now coming from Waitrose. Part of the reason behind this is due to the increased demand for Waitrose's own-label products, which are now understood to account for approximately 13pc of its total own-label sales. For the year to November 2011, consensus forecasts predict total sales for Ocado in the region of £600m, up from £551m in 2010.
