T&Cs copied from Cazoo to clear up your confusion:
2 Your Order
2.1 Your purchase details are specified in Your order confirmed on the Site ("Your Order") and will include the make, model, price, delivery or collection time and delivery or collection location for the car You are purchasing (the “Car").
2.2 Your Order will specify Your details as the recipient of the Car.
2.3 Neither You nor anyone in Your household may place more than one order in any 14-day period.
2.4 A contract is formed between You and us comprising Your Order and these terms and conditions ("Terms") when You complete an order on the Site and we accept Your Order (collectively, the “Contract") save in the event that You pay for Your Order using third-party finance introduced on the Site. If You enter into a third-party finance agreement to pay for Your Order, we will sell Your Car to the third-party finance provider – see section 5 below.
2.5 If we accept Your Order, we will send You an email confirmation of Your Order.
2.6 In the event of any conflict, inconsistency or ambiguity between Your Order and these Terms, Your Order will take precedence.
2.7 While we try to make sure that all prices on our Site are accurate, errors sometimes happen. If we discover an error in the price of goods or services You have ordered, we will tell You as soon as possible and give You the option of reconfirming Your Order at the correct price or cancelling it. If we can’t contact You, we will treat Your Order as cancelled. If You cancel and You have already paid, You will receive a full refund. If You cancel and You are financing Your Car, You will need to contact your finance provider to cancel Your finance agreement as set out in Section 12.
