Useless App

It took me a long time to log into my app for black Friday deals. I then selected items only to find out at checkout the price increased from what it was. The remaining items I wanted to purchase gives me an error only to confirm I cannot pay via credit or debit card. Absolutely useless and I am deleting this app because I just wasted my time waiting and still waiting to pay. I would like one of the directors to contact me and explain why this was such a nightmare to deal with..
