Children's clothing retailer Pumpkin Patch launched click and collect last year.
Powell said there was scope for The Warehouse Group to offer a single collection point for products bought online across the company's various retail brands, including Torpedo7, the online sports gear retailer it purchased a 51 per cent stake in this year.
