Amazon has Graco Atlas 65 2-in-1 Harness Booster Car Seat (Glacier) for $82.40. It usually sells for $102 (though the list price is $129.99).
The lowest price for this on Amazon prime day was $57.49. I missed the deal then but got this for $62.40 (with $10 Alexa promo, $5 Alexa GC promo and $5 credit for buying Amazon GC on Primeday)
Total price with discounts: $82.40 - $10 Alex discount - $5 GC discount - $5 Amazon GC credit = $62.40 + $4.52 (tax) = $66.92.
This is my first ever post; hope someone benefits from it as I have benefited from the deals on the site.
