This app can give you a promotion for free delivery for 30 days, let you go through until checkout, then finally say you are not eligible for the promotion (no reason given), then there is also no option to remove that promotion so, conclusion: no discount and you can't pay for anything for 30 days. I also got notifications for "discounts" that lead nowhere when clicked. Baffling. Finally, my review here was removed twice, so here it is again!
