When you place your bin booking at www.bookabin.co.nz you nominate the dates you need the skip bin for. Most hires last between 3 and 5 days, but you are able to book for up to 28 days if you need a skip bin for a longer period of time. The price that www.bookabin.co.nz  quotes includes keeping the skip bin for the number of days specified as well as the delivery, collection and disposal of the waste (up to 150kg per 1 cubic meter).
 If unforeseen circumstances mean that you have not finished with the skip bin on the nominated collection date, you should advise the supplier as early as possible. Provided the skip bin has not been booked out on another job, they can usually be flexible.
