FairUpsell adds one-click upsell offers to your checkout thank-you page and post-purchase screen, so customers can add another item without re-entering payment. It is priced as a flat $29 per month for unlimited orders, unlike apps that bill more as your store grows, including orders they never touched, like POS or wholesale. No ads are ever shown to your customers. If a funnel's product is removed or goes out of stock, FairUpsell emails you automatically so upsells never silently stop working.

• unlimited orders, even ones FairUpsell never touched
• Automatic email alerts if a funnel's product changes or goes out of stock
• Built-in A/B testing to compare two offers and see which converts
