As Amazon Prime Day rages on, rivals across electricals, entertainment and fashion have launched competing Sales initiatives in a bid to cash in on the retail event.

Currys PC World, which has gone toe-to-toe with Amazon on its annual Sales event in previous years, has tied up with Google to offer its customers a 48-hour black tag Sale event marking products down by up to 50% with free delivery.

Google mobile phones, home hubs and laptops are all discounted, along with bigger electrical appliances and computers.

Argos is also offering shoppers up to half price off a range of products across a variety of homewares, toys and electricals lines in a Sale event which ends today.

The Entertainer is hosting its own online-only ‘Deals Day’, giving customers 75% off selected items, While Robert Dyas is hosting a ‘Prime Steals’ Sales event which boasts “great deals for everyone, no subscription required”.

The retailer is offering discounts across gardening, home electricals, DIY and outdoor furniture categories.

As Amazon has focused on offering discounts across its clothing lines for this year’s Prime Day event, fashion etailer Boohoo has offered up to 50% off everything on its site in its ‘Get it or Regret it’ Sale.

Amazon’s annual Prime Day, which spans 48 hours this year for the first time, concludes at midnight tonight. The event, which raked in $4.2bn (£3.4bn) in sales in 2018, has been a source of controversy this year as thousands of workers across the etailer’s facilities in the US, UK and Germany stage protests over pay and conditions.
