Walmart’s summer sale has officially landed, both online and in stores. This event runs alongside Amazon Prime Day, so it gives shoppers a chance to shop further deals from another major retailer. Plus, it has the benefit of not needing a Prime membership to be able to shop the offers. Oh, and it runs slightly longer too, from 22 until 28 June. Over at Amazon, Prime Day kicked off on Tuesday, 23 June, and will run until 26 June, exclusively for Prime members.
