online SALE just time waisted

Advertising and punting an online sale starting at midnight, but not making sure your site can handle it... how unprofessional and clueless can you be in this times? Waited in vain, today 15 hours later it is still slow as a snail and utterley useless. Just frustrating and I have stopped trying. Also punting an online sale and when you click on a product that comes up... it is only available in store... Please just think next time and TEST your own website!, because you are losing customers this way.
