Online payments are a real win-win strategy. Less time, less hassle, less trash. For example, to buy a game online means no box and no computer disk, to replenish a mobile account online means no card covered with plastic. This week we are trying to live in the future.

Challenge #37
While accepting the challenge, we'll save 150 g of trash per week.
That is 15 kg, if at least 100 people accept it.
