Balance Bar

Question

Balance Bar is a protein bar. All athe ingredients seem OK. The only thing I'm worried about is the fact that on the label it says that the bar was manufactured in equipment that handles wheat, grains, etc. Is this OK for Pesach if I buy them before Pesach? (Batel Be-60) If it's not OK for Pesach, then should I wait a while before buying them after Pesach?
