- How does Dealophant calculate price per fluid ounce for contact lens solution?
- Total listing price is divided by the canonical fluid ounce count extracted from the product title. contact lens solution is best compared by volume (price per fluid ounce). 1 gal = 128 fl oz; 1 L ≈ 33.8 fl oz. Single-bottle pricing and pack count both lose meaning when bottle sizes differ across listings. Cross-unit listings (for example a serving-count tub mixed in with weight-based tubs) are shown separately under "Other formats" so the price-per-fluid ounce ranking stays apples-to-apples.
- Is bulk contact lens solution actually cheaper per fluid ounce?
- Usually yes, but not always — Dealophant has seen single-pack contact lens solution undercut bulk on a per-fluid ounce basis when the smaller size is on sale or has a Subscribe & Save discount the bulk listing doesn't. That's why Dealophant always recomputes per-fluid ounce price live rather than assuming bigger = cheaper.
