Sign up for Happiest Baby's newsletter to get a $20 off discount. However, the promo code only applies to orders of $199 or more, so it's most useful when you're planning a larger purchase.
When is the promo code actually worth using? It works best on smaller bundle purchases that just clear the $199 threshold, like a couple of sleep sacks paired with some sheets. We don't recommend using it on their bassinets since you can usually get a better value when they go on sale.
You have two reliable ways to join the email list. The first is to create an account on their website, which also makes order tracking and future purchases easier. The second is to tick the box next to "Email me with news and offers" when checking out as a guest.
Once you're subscribed, your welcome code arrives by email shortly after. From there, the newsletter also keeps you in the loop on seasonal sales and flash promotions.
Need more than just the SNOO Bassinet? Happiest Baby's bundles can be a smart way to save on essentials, with savings of up to 35% off when you buy multiple items together. The bundles include items like SNOO Sacks, fitted sheets, and other sleep accessories.
To put the savings in context, take the Big Bundle as an example. It includes three SNOO Sacks, one each in Small, Medium, and Large, plus two fitted SNOO sheets, all for $94.10. Bought individually, it would cost you $144.75, meaning that the bundle helps you save about $50.
That said, bundles aren't always the best move. They save the most when you actually need every item included. For those who feel like they would skip one or two of the included items, you're better off picking just what you need individually.
The Certified Pre-Loved SNOO can save you up to $500 compared to buying new, making it one of the easiest ways to get the same product for less.
Even though the bassinet itself is used, everything that touches your baby is brand new. Each unit ships with a new mattress, waterproof cover, organic cotton fitted sheet, and two organic sleep sacks. Before resale, the bassinet goes through a multi-step cleaning process that includes hospital-grade sanitization and a steam treatment on the mesh sides. This helps to remove allergens and irritants.
The units also come with the same 1-Year Warranty, similar to a new SNOO. If anything stops working as expected, you are covered.
In our opinion, the Pre-Loved option is a strong choice for parents who are looking to save. The few hundred dollars you save can go toward other essentials like a diaper bag or a stroller upgrade.
The 30-day trial on a SNOO purchase is a money-back guarantee, not a free loaner. Once you return it, expect a $199 restocking fee plus $59.50 in return shipping to be deducted from your refund. That's $258.50 in non-refundable costs, which applies to all purchased units, including Certified Pre-Loved models. Rentals are handled separately and don't qualify for the 30-day money-back guarantee.
For parents who are confident SNOO will work for your baby, buying it makes sense. The trial acts let you keep a product through the full bassinet stage, and you can resell it later. Promo codes also only apply to full purchases, so buying outright is the only path to get those discounts.
For those who are unsure, renting is the cheaper way to test SNOO. At $159 per month, a full month of use costs less than the amount you'd lose returning a purchase. Even renting for two months at $318 is barely more than the cost of a returned purchase. Plus, you avoid the hassle of the restocking process entirely.
Before deciding, take advantage of Happiest Baby's free sleep consultants. Their unlimited 7-day-a-week support can solve setup or sleep issues that would otherwise lead to a return.
