It depends on for whom and on what occasion. Chocolates and flowers for women are always good. CD's or DVD's might do for men. Soft animals are nice for babies and toddlers. For kids candy or toys will do the trick.
Everyone needs dish towels. Sometimes you can buy fancy soaps for about five dollars. How about a small box of chocolates? There are cute magnets that are cheaply priced Hand towels are also handy.
