Pumping moms (or moms-to-be planning on doing so soon), the must-shop sale you'll want to take advantage of right now is on the rarely discounted Elvie Pump.

The Elvie Pump is 20 percent off on Amazon right now for Prime Day. That means the double pump will be $439 (marked down from $549) and the single pump will be $240 (marked down from $300). You can also snag the similar Elvie Stride at a lower cost ($216 instead of $270).

Breast pumps are generally not the sexiest new-baby purchase. But if there ever was a cool breast pump, it would be the Elvie. One of the most popular wireless and wearable pumps on the market, Elvie nabbed a top spot on our list of the best breast pumps, and for good reason. Small and discreet, it can be worn inside your bra and is blissfully quiet, making it easier than ever for moms to pump wherever they are.

Not to mention, the Elvie is seriously high-tech. After each session, your data syncs to the Elvie app. Over time, you'll better understand insights like how much milk you express at different times of day, how long it typically takes you to pump and how fast or slow your flow is.

Of course, even with the discount, Elvie is pricier than many other breast pumps on the market. But if you're planning on pumping often, and if you envision that some or all of those sessions will occur somewhere other than your couch, an Elvie pump might be worth the investment.

During my nine-month nursing journey, I was fortunate to have both an Elvie and a Spectra S2 (the latter was covered by my insurance). While the Spectra S2 is incredible — it's a hospital-grade pump, and amazingly effiicient — it's big, bulky and roughly the size of a bowling ball. The Elvie, on the other hand, became my go-to whenever I needed to pump outside of the house (or around the house while multitasking).

While I found that I did need to pump a little longer to produce the same volume as the Spectra, it felt worth it to be fully wireless. Recharging the pump with a USB cord is also very useful; I loved being able to quickly power my Elvie from a computer instead of a wall outlet.

Because expressed milk collects in a discreet container built into the bottom of the pump (compared to traditional electric pumps, which collect in an exterior bottle, and even some other wearable pumps, which collect in a hanging plastic bag), the Elvie does not need to be used with a nursing bra and is truly hands-free. And since half the challenge for exclusively pumping moms is finding time and a quiet place to pump, I can imagine that the Elvie would also make it much easier to express while tending to your kids, making dinner or, you know, doing anything else that requires you not to be plugged into a wall.
