You have found an excellent holiday deal online!
You are keen to book it asap before all the places are sold out.
The answer was A and C
It has been reported that some bogus holiday websites claim that you have to pay by online bank transfer due to some insurance policy. Reputable firms would be expected to take usual methods of payment. Then in the event that it is a scam, the chances of getting your money back are best if you have paid by credit card. Paying by debit card is a better option than either bank transfer or cash.
