Consumer rights: top tips
1. If you buy goods on the internet you have the same rights as if you were shopping on the high street. In addition, you have the right to a seven-day cooling-off period from the date you receive the goods, with the right to a full refund regardless of the reason for return. However, this doesn't apply in some situations, for example if the goods were personalised for you, were perishable, or are not in the same condition as when they were delivered.

(1) Where the consumer exercises the right to reject goods
conferred under this Act, the consumer may choose to have—

(a) a refund of any money paid or other consideration provided
by the consumer in respect of the rejected goods; or

the rejected goods where such goods are reasonably
available to the supplier as part of the stock of the supplier,
and the supplier shall make provision accordingly.

(2) A refund referred to in paragraph (1)(a) means a refund in
cash of the money paid or the value of any other consideration
provided, or both, as the case may require.

(3) The obligation to refund cannot be satisfied by permitting
the consumer to acquire other goods from the supplier.

(4) Where a consumer obtains goods to replace rejected goods
under paragraph (1)(b), the replacement goods shall, for the purposes
of this Act, be deemed to be supplied by the supplier, and the
guarantees and obligations under this Act relating to the supply of
