Appalling bad
Wow. After how many years of Apps, Coles came up with this absolute rubbish. Touch anywhere on the screen, something opens that you didn't want. Want to scroll? Sorry, no, some random thing will open. This is what you get when you get the trainee to design something on a zero budget, a totally unusable, awfully designed app. I'd give it zero stars but you cant. For all the price gauging they do you'd think they'd use some of the enormous profits for something good and actually test it.
