Can I buy from internet?

Cash On Delivery (COD) was widely used before Credit/Debit Cards. It is unlikely that any Website would still accept this method of Payment (contact them for confirmation). The main reason is the Security of the person making the Delivery (Cash Collection). And the facts that it costs the company money to pay into their Bank Account meaning Extra Staff and there will also be an element of dishonesty (thieving), meaning the goods price is inflated to compensate. Get yourself a CREDIT or DEBIT Card ASAP
