Target offers the LEGO Dimensions Starter Pack for PlayStation 4 or Xbox One for $49.99 with free shipping. (Best Buy and Amazon charge the same on both platforms.) That's the lowest total price we could find by $10, although we saw it for $5 less in July.
Of note, Target, Best Buy, and Amazon each offer it for Xbox 360 for $39.99 with free shipping. That's the best deal we could find for this version by $10.
