10 things to watch out for when... Buying mail-order goods

The pros: Mail-order shopping is not very popular in Hong Kong as most things are readily available at street level, according to W.K. Chan, head of the Consumer Council's complaints and advice division. The main attraction is the convenience. Shopping this way can be done 24 hours a day, within the comfort of your own home. It saves transport costs, the effort of carrying bags home and having to deal with crowds.

The cons: Mail order is most popular when buying clothing, computer software and CDs. But tiny catalogue photographs can hide a multitude of defects. You can never be sure that the item is exactly what you want until you see it in the flesh. Sizes, colours and quality of fabric may not meet your expectations. Check that software is compatible locally before ordering.

Reputation: Deal with known, reputable companies that give a physical address, not just a post box number. If you are uncertain about catalogue specifications, write or e-mail before you order.

Return to sender: Check the company policy to ensure you are able to return goods with a full refund if they are unsuitable or damaged. Companies usually specify a time frame for returning goods. If you return goods, keep the postal slip.

Shipping: Calculate shipping costs which can drive up the price significantly, depending on where the goods are being sent from. Check who bears the cost of returning goods.

Warranty: Read the warranty carefully as there are often disclaimers. Defective goods may have to be returned to the manufacturer in another country. Some companies require you post proof of delivery within a certain time frame to activate the guarantee.
