I read this online and I loved the idea, since this series is almost over, BB should set 5 final tasks, for their last luxury shopping budget plus a party but also for each task they pass BB would refund 10k so if they pass all of it, it would be again 100k, they wouldn't pass all of them but it would guarantee at least 10k extra in the prize fund. BB wouldn't tell this to the housemates until the last moment when he reveals if they won the luxury budget+party or not.
