Big Red Special, Oh sorry, NO STOCK! this is BS!

I fully understand the special: while stock last. BUT DONT TELL me you don't have stock just a while after the store opened and you don't want to disclose to me the amount of stock you had... this sounds to me like 'Fishing Adverti*****t' and something that is against CPA!!!! UNACCEPTABLE!!!!! Thank you very much for wasting our time, money and effort for driving to your store for NOTHING!!!!
