When you place an order for eligible products online, you will be offered the option to have your order delivered to your local Mothercare store. Orders will usually be available for collection from your chosen store from the next working day (However please note at busy times the Click and Collect date may be extended) – you will receive a text confirmation when your order is available for collection. Please be advised that we will hold your order for a maximum of 7 days, after which time your order will be returned to our warehouse. This service is available in the UK.
