Example use cases
Amazon multipack discount strategy
“I sell a single protein bar for $2.50 on Amazon — can you run the Friday Seller Tools bundle-multipack optimizer to figure out the ideal pricing for a 12-pack and 24-pack so I stay competitive but protect my margins?”
Cross-marketplace bundle pricing
“I want to list a skincare bundle (cleanser + toner + moisturizer) on both Walmart and Shopify — use Friday Seller Tools to calculate the best bundle price given the individual items cost $12, $14, and $22 separately.”
Multipack price ladder for eBay
“Can you help me price my phone case multipacks on eBay? Single unit is $8.99 — I need optimized prices for 2-pack, 5-pack, and 10-pack options that'll drive volume without killing profit.”
