At least two members on here have ordered from Halfcost recently and have been supplied with what appear to be fraudulent tracking numbers. They don't exist according to the delivery company and Halfcost initially gave some unbelievable excuses by e-mail. They have failed to answer the phone and my last two e-mails have been returned as the domain name doesn't exist.
Both of us have had to make chargebacks to card companies and my card issuer is investigating them for fraud.
Personally I would steer well clear of them at the moment.
