Thumb Score: +1

Many people have noticed that Graco is now offering extra 25% OFF on sale item, which is ending tonight. Use code: SALE25

I find this car seat is really good and the price is also beautiful.

Extend2fit 3 in 1, an enhanced version of Extend2fit, which includes a back-support booster.
Well, it does not include backless booster, which is included in Extend2fit 4ever. But it is at least $ 100 cheaper (comparing to Used Like New sold at Amazon) and I do not see any other difference between them.

The only cons are the fussy Graco return policy.
