Replacement NutriBullet cups are available through Amazon, NutriBullet and Bed Bath & Beyond, as of 2015. The deluxe upgrade kit includes a 24-ounce cup, an 18-ounce cup, a regular lip ring, a handed lip ring and an additional extractor blade, which NutriBullet recommends replacing every six months.
A 24-ounce cup with matching lid or handed lip ring also is available as a separate purchase. All NutriBullet cups are BPA-free and dishwasher safe, and they carry a one-year manufacturer's warranty. The NutriBullet site also sells an insulated bag that holds one cup and a travel bag that holds an entire NutriBullet system.
