This is HUGE for kids. Nasal spray as a delivery method is a big step up from needles, the shelf life is much longer, it's less susceptible to high/low temperatures, and if the promotional pricing is accurate, it's cheaper than EpiPens and Auvi-Q (which talks you through the injection procedure).
I wouldn't be surprised, though, if insurers continue to push generic epinephine injectors ($15-$30) merely from a cost perspective.
