Website is offering to let me negotiate with an AI to buy a mattress

It’s much simpler. There is no actual floor, but you won’t be able to claim it if it displeases the owners.

This is more of a marketing move than actual negotiation. It's similar to how companies give out first order discounts, or have general coupons for 5% or 10% off.

Just added layer of AI chat to negotiate to engage the users and give a sense of power over the price while there's already a cap at how low the AI can go.
