I've been meaning to update about this. "poobear" baby bargains forum member helped me get THE BEST DEAL on a Britax...but the codes will work on other seats as well....
I bought a Britax Frontier 85 (regularly $279) for $166 and I got a free pack of diapers.
Here is how I did it.
#1. Sign up for Bing Cashback.. They will put your money in paypal for you, or I think they can send a check. If you don't have a windows live ID...Just sign up for a hotmail email account and then you will have one...Then you can sign up for Bing Cashback. Complete the Bing registration process through your hotmail or windows live account.
#2. Find the product you are looking for on sale at another website. I used Hipmonkey.com they have a coupon code right now "20thanks".
#3. Register for an account at Diapers.com, I used my new hotmail email account to register so the bing cashback would all be in the same email but I don't know if it was necessary.
#5. Call Diapers.com and tell them that you want a price match. When I did this they looked on the hipmonkey website and saw that the 20thanks code gave a $56 discount on my carseat...so they just added $56 to my account. I told them that I wanted to browse the website and check out online.
#6. Search for your item using the Bing Cashback Search Engine. . Find the diapers.com link (mine was right at the top of the page as a sponsored link when I searched the word carseat through bing). Click on the diapers.com link through bing and when you checkout at diapers.com you will get your bing cashback notice in your email.
#7. Log into diapers.com and add the item to your account. I was a first time customer at diapers.com so I used the code "PLUS10PCT" for additional 10% off your first purchase. I think you have to buy diapers, and spend more than $49 for this code to work but you can use a referral code and get them free...I added a $9.99 pack of Huggies and the referral code I used gave me $10 so they were free. Search www.retailmenot.com for referral codes.
#8. I'm not 100% sure this is still available, but I filled it out and sent it in anyway....diapers.com gives you a free subscription to Parenting magazine with your first order...You can fill out this rebate to send in and get $10 back instead. It was $15 when I ordered?
So here is the breakdown of my deal:
$279 carseat
-$56 for hipmonkey price match
-$22 for 10% diapers.com code
-$20 for 10% bing cashback
-$15 (now $10 sorry) for Parenting Magazine rebate
plus free 2 day shipping
=$166 and a free pack of diapers.
Yay!!!!
