  We study how to compute the operator product expansion coefficients in the
exact renormalization group formalism. After discussing possible strategies, we
consider some examples explicitly, within the $\epsilon$-expansions, for the
Wilson-Fisher fixed points of the real scalar theory in $d=4-\epsilon$
dimensions and the Lee-Yang model in $d=6-\epsilon$ dimensions. Finally we
discuss how our formalism may be extended beyond perturbation theory.
