  Following earlier one-step calculations, we explore the contributions of
multi-step effects for the breakup of low energy $^8$B on $^{58}$Ni and
$^{208}$Pb within a coupled discretised continuum channels (CDCC) formalism.
The Coulomb multi-step differential cross section is significantly reduced for
all angles, the largest effect being the destructive interference of nuclear
couplings. The nuclear peak, at around $80^\circ$ in the one-step calculation
for $^{58}$Ni, virtually disappears.
