Basically, Ark will need to deliver the goods within 30 days or they're going to have a small legal issue to deal with thanks to the Consumer Protection (Distance Selling) Regulations 2000, regulation 19 which allows a consumer to receive a full refund if the goods are not delivered within 30 days.
19.—(1) Unless the parties agree otherwise, the supplier shall perform the contract within a maximum of 30 days beginning with the day after the day the consumer sent his order to the supplier.
(2) Subject to paragraphs (7) and (8), where the supplier is unable to perform the contract because the goods or services ordered are not available, within the period for performance referred to in paragraph (1) or such other period as the parties agree (“the period for performance”), he shall—
(a)inform the consumer; and (b)reimburse any sum paid by or on behalf of the consumer under or in relation to the contract to the person by whom it was made.
