Oasis has replatformed its website to improve the user experience for customers and bring it in line with sister retailer Warehouse, which made the move a few weeks ago.
The two chains worked with Accenture Strategy’s Javelin Group, Demandware and Retail Assist to manage the online migration.
The new, responsive sites offer improved delivery options, as well as a wish list and “quick view” feature.
Shoppers can filter a category to see what is available in their nearest or favourite store, or to see if that store has a particular item in stock.
They will also offer online receipts in the near future.
Oasis and Warehouse chief operating officer Hash Ladha said: “Across each brand we pride ourselves in consistently being at the forefront of innovation and now have a new base to continue to build from for the future.”
