Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureBlanket discount codes give away margin to shoppers who would have paid more, and you can't negotiate with every visitor yourself. Flux adds an AI agent to your product pages. When a shopper hesitates, it invites them to talk price, then negotiates in real time in your brand voice, never below the hidden price floor you set. Offers under your floor are saved for you to approve or decline.
Nibble’s AI chatbot discovers the deal your customer needs – and balances it with the discounts and offers you’re willing to give. Existing clients have used Nibble for success in B2B, high-value items (like furniture), resale, and MAP-regulated industries to offer unique pricing to discerning customers at scale. It is highly customisable and targetable.
