Britax Roundabout $100 and Marathon $159 at Target

Target has selected patterns of the Britax Roundabout for $100 and Britax Marathons for $159. Different stores seem to have different rules on which patterns are included. Also, it sounds like some BRU and TRU are allowing a price match with a copy of the Target ad. Some are even allowing price match and letting you use their 15% off car seats coupon.
