Tony needs a ladder for a week to do some painting, and wants to rent one instead of buying one. Tony goes on to www.rentmystuff.ie to search for a ladder near where he lives.
Sarah has a ladder that she doesn't use very often and she's willing to rent it out to people to make some money. She has advertised the ladder on www.rentmystuff.ie.
Tony finds Sarah's ad on www.rentmystuff.ie. The ad shows a ladder for rent for 2 euro per day and a deposit of 60 euro and it's walking distance from his house.
Tony contacts Sarah and the ladder is available the week he needs it. They meet and Tony gives Sarah 74 euro and takes the ladder for a week. 14 euro is rent and 60 euro is a deposit.
After a week, Tony returns the ladder to Sarah. Sarah sees the ladder is fine returns the 60 euro deposit to Tony.
Sarah has made 14 euro for herself. Tony has saved money by not buying a new ladder.
This site helps people that need to rent stuff (rentees) to get in touch with people who have stuff for rent (rentors).
In this example Tony is a rentee and Sarah is a rentor.
