Large-N expansions are usually applied in single-well setups. We claim that this technique may offer an equally efficient constructive tool for potentials with more than one deep minimum. In an illustrative multi-well model, this approach enables us to explain the phenomenon of an abrupt relocalization of ground state caused by a minor change of the couplings.
