Well, from what we now know about Amazon's warehouse, it may have been exposed to extreme heat. But I think it's primarily the body acids and oils that degrade helmets; IIRC even if the helmets were in those particular warehouses, the temperature topped out around probably 120°F.
Moto helmet manufacturers usually talk about the hats being good for five years from first wearing or seven from date of manufacture, whichever is earlier. I wouldn't worry about it (but I probably would consider warehouse conditions as another reason to buy a helmet from a LBS whenever possible - and I'd probably replace it after you've been wearing it for three years, rather than try and stretch it a year or two as a lot of people do who question why certain bici helmet manufacturers changed the limit from five years to three).
