недавно пытался на ибей применить какой-то купон, но он не сработал, а потом мне от них письмо пришло с персональным купоном: "We recently issued an incorrect coupon due to a technical error. We’re sorry for any confusion this might have caused. You were meant to receive a personalized offer of 10% off your next purchase, up to a maximum discount of $20."
