The research, plainly
Prelec and Loewenstein modeled the psychology of transactions: each payment moment triggers a distinct sting, and decoupling payment from consumption — prepaid, bundled, invisible — makes the same total spend feel dramatically lighter.

What it means for events
Nobody should do math at your event. Every itemized charge — the cash bar, the paid add-on, the surprise fee — is a fresh sting billed against the experience. All-inclusive isn't generosity; it's anesthesia, and it makes identical spend feel like hospitality.
Where to run it
Pricing architecture
One number, everything in. The itemized invoice and the all-in invoice cost the same and feel worlds apart.
On-site experience
Cash bars at hosted events are sting machines. Pre-fund the experience or don't offer it.
Sponsor packages
Bundle the add-ons in; the à-la-carte sheet makes partners feel nickeled at every line.
