Knitwear can help you feel warm during the cold winter months, but customers of a new Swiss website will feel even warmer with the knowledge that their woolly socks have been knitted by a grandmother. Brainchild of the Basel-based fashion brand Tarzan, the NetGranny.ch website even lets visitors choose which granny they want to do the knitting – a level of personal service often unassociated with online retailers. Websites can offer greater interaction with consumers in this way to enhance the typically one-dimensional process of purchasing online.
