Price per label serving: bind both inputs

Use the checked pair

ON Banana Cream,29servings/2lb, SKU1171462 was listed at$74.49 in the US feed. Dividing by29 gives about$2.57 per label serving. This is a dated observation, before tax and shipping, not a completed checkout.

Round only at the end

The rendered merchant page showed$2.56 per serving, while exact division rounds to$2.57. We retain our stated rounding method rather than silently adopting a truncated merchant ratio. Tiny rounding differences are not savings.

Avoid a nutrition ranking

The lowest serving price may use a different powder mass or protein amount. Keep those fields visible and compare products on the criteria relevant to the purchase without turning a label ratio into a medical or performance recommendation.

A practical record to keep

A delivery charge changes cost per serving even if the product sticker does not change. For example, an actual checkout total can be entered instead of the product-only price, provided the comparison uses that same cost scope for every row. Keep the observation date and the selected flavor beside the result so a later price refresh does not mix incompatible records.

Before you decide

• Keep the exact selected label and variant
• Separate observed facts from your assumptions
• Refresh current product and checkout information
