Key reasoning
Purina Pro Plan is a Chewy Autoship favourite. Purina is one of Chewy's most-Autoshipped brands. Autoship first delivery: 15-25% off typical, 35% during promotional windows. Subsequent Autoships: 5% ongoing.
Amazon Subscribe & Save loses on Purina Pro Plan. Amazon's 5-15% subscription discount is less generous than Chewy Autoship's 15-25% first delivery. Amazon's ongoing Subscribe & Save on Purina Pro Plan is typically 10-15%; Chewy Autoship's ongoing 5% plus ShopBack cashback closes that gap.
ShopBack cashback compounds. First order via ShopBack: 10% cashback boost (up to $10). On a $100 Purina Pro Plan first Autoship, this returns the full $10 cap. Subsequent orders: 3% base cashback.
Bag size drives per-pound cost. Chewy sells Purina Pro Plan in 6lb, 16lb, 24lb, 34-47lb bag sizes. Larger bags = lower cost per pound. Buy the largest bag your dog can consume within Purina's freshness window (typically 3-6 weeks after opening).
Formula choice is nutrition, not price. Purina Pro Plan Sensitive Skin & Stomach, Sport 30/20, Bright Mind Adult 7+, Focus Puppy โ all Autoship-eligible with the same 15-25% first-delivery discount range. Vet advice governs formula; cashback math applies equally.
