I am sure QHI will except a cheque or a postal order from your post office, or just send them cash (don't forget to send it registered post!)
Where you just planning to just use finasteride for a few weeks or long term ?
Are you willing to pay above the going rate or would you just like the people on here to do the donkey work of purchasing for you ?
If you plan to use finasteride long term I would think asking around on hairloss forums for people willing to sell you some of their supply everytime you run out of the medication would be inconvenient at the very least and would only lead to a very inconsistent supply.
