<prompt> Human: Answered- and seem to be good solutions. I have a college student and we would like to budget gasoline separately from other needs. I know that we have given away grocery gift cards that were restricted to food only so I assume there is something out there that will work. I have already researched some prepaid cc companies that deal in fleet type cards but they have minimums; this is for one person.Edit - I appreciate the comments, however, my question was not should I force a budget on my college student. I am going to regulate how he spends his money because this is a growing problem in our country. I wouldnt give him a no limit credit card and it has nothing to do with trust. Learning by mistake has been ruining futures for our young people for many years. He can make mistakes with his own money, not with mine.  <response>: I dont think this is a good idea. Like other poster say. If you dont trust them dont give it to them. What is to stop them from reselling their gas at a discount in order to get real cash? Fill your tank for a case of beer buddy? Remember money is fungible. But most importantly distrust builds resentment.
