  Contact terms in two point functions of global symmetry currents have
recently been proposed as a check of Seiberg-like duality in three dimensional
supersymmetric field theories. In this paper we compute the contact terms for
various N=2 dual pairs in flat space. We show that the results of this
computation agree with the ones obtained from localization. We study dual pairs
of gauge theories with (anti-)fundamental matter fields, and some special
examples of dual pairs with adjoint and antisymmetric matter fields. We also
propose a duality between unitary and symplectic gauge theories.
