Sale season on High Street is well defined — usually a few weeks each in January and July. The ongoing festive season is when brick-and-mortar retailers lure gift-hunting shoppers with greater variety, not lower prices. That’s not how it’s in the online universe, though. Starting Eid in end-August, until Diwali in mid-November, your inbox is likely to be flooded with mails from e-retailers, offering special deals, season-specific products and, most importantly, discounts. Many shopping sites have also decked up for the season, changing the look and feel of their sites for each festival.
