Task 2 Read the passage about tips for shopping online (part 2) and choose the correct answer.Tip 2: When you start shopping, know what you’re looking for. This way it will be easier to ignore the other things that you really don't need. Also, remember how much you want to spend and don’t go over your limit. The shopping cart may be virtual, but that credit card bill you get at the end of the month is 100% real. Tip 3: Read the reviews. I know that is boring but you have to research. It will save you a lot of disappointment. There have been lots of instances where you get a size medium and turns out the dress fits like an extra-large in real life. It always helps to read the reviews because people love to complain about products. Listen to them! They’ll save you lot of time and money. You will just have to send the item back otherwise.Tip 4: Check for hidden costs before you buy. The $20 T-shirt you like could turn into a $40 T-shirt if the shipping charges are high.Tip 5: Better safe than sorry! Check if you can return the item and if you have to pay for the postage. If there isn’t a return policy, or if there is a charge for returning the item, it is better to know now than be unpleasantly surprised later. Choose the correct answer.What must you check before you buy an article?
A.
You must check if you have to pay for the item.
B.
You must check if you can pay.
C.
You must check if you can pay by credit card.
D.
You must check if you can return the item.
