Just gone through (another) painful process of shopping online at ASDA, I am now compelled to share my frustration. ASDA has the worst online shopping website I have dealt with in a long time: 1. Behaves completely different between Explorer and Firefox browsers. 2. Page does not return when incementing an item's quantity 3. If you page to next page on shopping list before adding the first page to the trolley, you lose all your selections on the first page. 4. Selects "replace with alternative product" is switched on by default, so if you do not want to replace your products with alternatives, you have to deselect EVERY item in your basket. No global deselect. 5. Doesn't recognize my userID (email) on Firefox, but does on Explorer. It is clear that the developer/s of this website is not competent to develop a professional website. ENOUGH!! I will give TESCO a try from here on.......
