It depends on the products in your basket. If all the products in the basket are from the same brand, then the pick-up options will be the stores from that brand. If this brand is one of the Centrepoint brands, Centrepoint stores will be offered as additional pick-up points apart from the brand stores.
For multi concept basket, Click & Collect will be offered only if all the concepts are part of Centrepoint (Mothercare, Lifestyle, Splash, Shoe Mart). In this scenario, your pick-up point will be only Centrepoint stores.
During checkout you will only see the stores which have Click & Collect available.
