Useless to say the least

Tried to purchase several items on the app. Including 1 hour 1 pm, black Friday deals, normal deals and 100% off deals. Nothing is adding in my cart and it keeps no giving me a error message that the system is identifying me as a robot. ***?? Missed out on so much cause of a *********** app! They should really look into this as they will loose many clients. What a dissapiontment.
