Can I pick up and pay for my order at one of the stores?

You sure can! When you've finished adding items to your shopping bag, select collect at a store on the shipment page. Then select which store you would like to pick your order up from.
When you get to 'how would you like to pay for your order' you can click on the option to pick up your order at a store. Your order will then be switched to a reservation, and you'll receive an e-mail as soon as your items are ready to be picked up. You can pick your items up within 7 days. It takes on average two working days for your reservation to be processed. If some items aren't quite what you'd hoped for you can leave these behind and only pay for the ones you want to take with you!
