Sainsbury's, a large grocery company, has been developing its brick and click operations to provide better services to customers. The brick operation includes introducing new self-checkouts, smart shopping apps, and moving the bakery and frozen aisle to improve customer experience. Additionally, Sainsbury's has improved its fridge system using aerofoils technology and implemented recycling old crates for new ones made from 100% recycled materials. In terms of click operation, Sainsbury's has been investing in its online website, providing click-and-collect services, and improving its website design and functionality to cater to customers' needs. However, it seems that the company is still focusing more on its brick operations rather than equally developing both.
