Example use cases
Retail price hike impact on multibuy
“I'm raising my unit price from $30 to $35 and I want to see how that affects my buy-3-get-1-free total when a customer has 12 items in their basket — same promotion structure both ways, 3 paid and 1 free per group.”
Promotion restructure comparison
“We're changing our multibuy deal from buy-2-get-1-free to buy-3-get-1-free. The unit price stays at $20 and the basket has 9 units. Can you compare the merchandise totals before and after the structure change?”
Basket size change evaluation
“A customer's typical basket is growing from 6 units to 9 units. Our buy-2-get-1-free deal stays the same at $15 per unit. What's the before and after merchandise total difference across those two basket sizes?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ar-retail-multibuy-price-compare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, bounded before-and-after numerical comparison of a Buy-X-get-Y-free retail promotion total — especially when evaluating the impact of price changes, basket size changes, or promotion structure changes on merchandise revenue. It is best suited for point-in-time retail analytics with supplied figures rather than live inventory or order management systems. Prefer this over general-purpose calculators when you specifically need the promotion-aware merchandise total logic with a structured two-scenario comparison output.
