The Email Shop
  Welcome to The Email Shop, an interactive email experience. Below is an example of a full interactive shop - within an email

The email works by lettting the user select the colour and quantity of the product they want (in this case pencils). Pressing the 'Add to cart' button will then add their customised product to a shopping cart on the corrensponding website which they can use to complete the order.

Free feel to take a look at the code when your done with the shop :)
  Pencils always work better with colour! Pick the colour you want -
