Paying for on-line purchases without a Credit Card is possibly one of the most dangerous ways to buy things anywhere.
You have NO recourse if the items are not delivered, your account will be billed, period.
There are a few companies who still honor COD,
www.compgeeks.com will do this and the fee is reasonable.
Get the credit up, after having a couple of cards, apply for the American Express "Blue" card, it has benefits not equaled by any other CC in the industry.
