Should presents be a thing of the past?

During the holiday season, vendors sometimes send me presents to thank me for the opportunities I've given them throughout the year. Management allows me to accept these gifts, but some other people at my company don't seem too happy about them. Should I share food items and maybe divvy up other gifts among my coworkers? Keep everything for myself? Or is there another way to handle this situation?
