Progeny Apps / State laws, fees & selling rules / Shelftag
For shopify merchantsThe price per unit, beside every price.
Shelftag works out the unit price of each product, the selling price divided by its net quantity, in the one unit you choose for that category: per ounce, pound, fluid ounce, count, square foot or metric. It flags a category that mixes units for like items, or uses the wrong kind of unit. In the places NIST lists as requiring unit pricing, the unit price always shows; elsewhere you decide. A preview shows what a shopper in each state sees. Display rules are yours to check. Not legal advice.
