Shop Guide UK exists because the answer to a simple question — will it arrive on Saturday, can I send this back, why was my payment declined? — is usually scattered across a help centre, a forum and a page of small print.
Here it is in one place and in plain English: the answer first, then the exceptions, with the figures where there are any. The guide is arranged like a department store, by the shops, marketplaces, couriers and ways of paying that people in Britain use.
Shop Guide UK is independent. It is not a retailer, a marketplace, a courier or a payment company, it is not affiliated with any of the businesses it writes about, and it cannot see or change an order. Policies change: before relying on a figure, check the company’s own website, and for your legal rights see the official guidance from GOV.UK and Citizens Advice.
