Any guesses on Mother's Day sales? Olympus $150 40-150 deal w/ purchase of a PEN body ends tomorrow. Should I get it now w/ the E-M5? or wait to see what kind of Mother's Day sales they might have? Or Pre-Order tomorrow (4/21 deadline), wait till Sunday and see if they have new promotions and quickly cancel if they do? LOL. There's a Black E-M5 w/ 12-50 lens calling me!
