VendorButton Advantage connects vendors’ sites and shows their own relevant products first on thank-you pages after purchase. A $19 one-time founding membership includes five sites and 200 offers, with no recurring membership fee for the operating life of the service.

Private mode: New sites start private with network fallback off. Private, own-offers-only mode prevents other vendors’ offers from appearing on that site and keeps that site’s offers within the account. Individual product, website, and affiliate offers can also be private. Sharing offers and receiving network recommendations are separate controls. Existing sites retain their saved settings.

Site statistics: Each site reports observed recommendation impressions and outbound clicks for the last 7 and 30 days, plus a 30-day click rate. Click rate is clicked recommendations divided by observed recommendations. Repeated clicks on the same recommendation count once. These are recommendation events, not unique buyers, sales, or revenue attribution.

Offers match configured niche tags and vendor priorities. Network fallback is optional and applies only when no relevant own offer qualifies. Nothing appears without an eligible offer. The widget does not collect buyer names, emails, or contact lists or require third-party cookies or customer profiles. A visitor who clicks an affiliate or network offer visits its destination, whose privacy and marketing practices apply. Private mode does not guarantee customer exclusivity. Membership does not guarantee traffic or sales.

Security: The recommended embed is a cross-origin sandboxed iframe without allow-same-origin, forms, or top-navigation permission. It cannot read the parent page’s buyer email fields, DOM, cookies, or storage. Existing users must remove old external VendorButton scripts and use the new iframe snippet. Leaving a legacy script installed preserves its page-level access. The boundary does not prevent a visitor from voluntarily sharing information with an offer destination.
