NCrowd has foreclosed according to the source below. NCrowd currently doesn't sell any goods or services. I would recommend that you request ASAP chargebacks from your credit card company for all nCrowd vouchers that can't be redeemed and for unused store credit (which is now useless). The fraudulent people who own nCrowd has now rebranded and launched a site called www.boomstreet.com. I would avoid doing business at all costs with Boomstreet if I were you.
