Start with the exact pair
Eco-Products’current EP-BHC12-WA cup page lists EP-ECOLID-W among its compatible lid codes. At the selected retailer, the cup offer is 1000 cups per case and the white EcoLid offer is 800 lids per case. The shared manufacturer relationship does not make their selling quantities equal. Keep those two package counts beside the price before planning a covered-cup purchase.
Work through a chosen target
With a user-chosen target of 1000 covered cups and no held stock, one cup case supplies 1000 cups. One lid case supplies 800 lids, so 200 assemblies lack a lid. Rounding up requires two lid cases, which supply 1600 lids and leave 600 above the target. That is whole-case arithmetic, not a prediction of loss, use frequency or how many days the inventory will last.
Use one-time prices consistently
The selected observed one-time cup price is 146.37 USD and the selected lid price is 122.94 USD. One cup case plus two lid cases therefore has a known merchandise base of 392.25 USD before unknown charges. The page also presents subscription options. Those recurring-plan prices are not silently substituted into a one-time basket, and no subscription is created by this site.
Distinguish capacity from count
The lid’s 10–20 oz family description is about its intended matching cup family, not the number of lids in its case. It does not mean a 12 oz cup needs 1.2 lids or that an 800 lid case contains 800 covered cups. Counts are whole physical items. Nominal beverage capacities never become a multiplier for lid quantities in these tools.
Plan around actual inventory
If 800 matching lids are already held and the chosen target is 1000 complete assemblies, only 200 morelids are wanted. A whole 800 case still creates surplus relative to that target. The tool shows the difference without recommending a stock reserve or assuming held lids are clean, undamaged and the correct code. The user must count actual usable matching stock privately.
Confirm the received codes
The retailer describes the current lid quantity as 800. Do not borrow a 1000 count from another supplier, older catalog or a different lid product. Verify the actual selected option at checkout and the received carton before treating the basket as complete. Unknown shipping, tax, stock changes and independent product review remain separate from the arithmetic.
Retain the remaining inventory
For the 1000 cup/1600 lid example, the 600 extra lids remain a separate stock line. They are not additional covered cups without matching cups and do not establish a future reorder date. If a later target uses those lids, the user can count the actual usable code-matched stock before calculating another whole-case purchase. Do not divide their cost by an invented daily demand rate. The apparent high initial basket cost partly reflects the mismatched selling quantities, which should stay visible rather than being averaged away.
Keep the maker lid fields unresolved
The current EP-ECOLID-W maker page names a White lid and describes PLA,while structured fields say Raw Material CPLA and Material Color Clear. The selected retailer offer is the White code. This source-field difference is retained rather than harmonized into an invented formulation or color explanation. The maker also lists a200°F maximum-temperature field for the lid,distinct from the cup’s185°F field. Neither is a complete exposure or handling protocol. Ask the manufacturer about the exact current version before relying on those unresolved technical fields.
