A workflow which works
Give your customer the shipping option or method "ship to store" without any shipping cost in your ecommerce store. Based on the delivery/shipping address let show the right store near to the customer.
Not all big retail brands worked with this method in their online stores and we always ask the question "why". Sent your customer an email or sms about the delivery of their ordered goods at the store. This method is very successfull and if you spent them a little discount for that, too you are the "superman/woman" of shopping success stories.
Not all clear how to implent this in a magento shop? Ask us via email and we give you the right way of work.
