Your rights to have a delivery price honoured
Contractual Rights
Typically in internet shopping, a buyer enters into a contract to buy goods for a total amount that involves the price for the goods plus a delivery charge. Once a contract has been formed with a set total price, the seller has a legal obligation to honour this price and the buyer has a right to have the goods delivered at that price.
Example
Attempt to increase delivery charge after sale
A consumer visits www.laptops123.com, selects a laptop and follows the online buying process to its conclusion, entering card details to purchase the goods. The company sends an email from laptops123.com confirming the purchase for £400 plus £9.95 standard UK delivery. The company sends another email two days later seeking an extra £25 for delivery, resulting in a total price of £434.95.
Consumer Rights
Consumer has right to receive the goods for payment of £409.95, or to cancel the purchase.
