What if you want to offer deliveries on your online booking wizard?

You can, but you have to bear in mind there are operational complexities that you need to consider:

  1. what is your pricing policy?  (how do charge?  based on distance?  number of bikes?  combination)
  2. what is your 'range' policy?  (how far afield do you deliver)
  3. what about the place of pickup / return.  (particularly if you have multiple locations)

Some people use 'extras' to allow the customer to request delivery.  However you will have to manually take care of the above considerations.
