How to deal with cheap people
Include this person in the planning.
Whether you're planning an outing, a group trip or going in on a gift for someone, make sure to include this person from the beginning. If they are a part of the planning, they'll be able to tell you what their budget is and what they are able to contribute.
For example, let your cheap sibling be the first to know if you're thinking of doing a group gift for your parents. If they want a less expensive option, they are able to suggest ideas themselves.
