The RedFlagDeals.com forums are buzzing about the great deal on the Britax Marathon 65 Car Seat at Amazon.ca. It's currently $199.99 which is $100 off list price. It's a very well-rated and well-reviewed car seat that works both rear- and forward-facing and accommodates passengers from 5 pounds all the way up to 65 pounds. With that weight range you could easily get four or five years of use out of it.
The seat is available in
three colours one colour -- the others have sold out -- and comes with free shipping.
