Frequently Asked Questions
Can I list single items as well as multi-item bundles?
Yes, absolutely! Bundle Buddy features a comprehensive Single Item Listing tool. You can scan barcodes with your camera, pull catalog details, run real-time competitor price intelligence, generate AI copywriting, and publish or revise live eBay listings directly from the app.
How does Market Price Intelligence work?
When you scan a barcode or enter an item title, Bundle Buddy queries active and recently sold eBay listings matching your product. We calculate the Market Low, Median (including postage costs), and Market High, plus a smart recommended price that undercuts the market median for maximum sales speed without sacrificing profits.
Can I copy photos and titles from competitor listings?
Yes. If your listing doesn't yet have custom photos or only has a catalog dummy cover, you can click "⚡ Use Title & Photos" on any competitor card in Market Price Intelligence. Bundle Buddy instantly copies their title and fetches high-resolution 1600px eBay photos into your draft.
Which international eBay marketplaces are supported?
Bundle Buddy natively supports 8 major eBay marketplaces: United Kingdom (GBP), United States (USD), Germany (EUR), Australia (AUD), Canada (CAD), France (EUR), Italy (EUR), and Spain (EUR). All carrier options, postal rules, and currencies adapt automatically.
Does dual-listing risk selling the same item twice?
No. When a single listing in a dual-listed bundle sells, Bundle Buddy's real-time webhook engine detects the sale instantly and revises the bundle listing on eBay to remove that item and update the price. If only 1 item remains, the bundle is automatically closed (set to quantity 0) leaving only the solo listing active.
How does the Free Tier watermark work?
The Starter free tier includes a discreet footer badge at the bottom of bundle descriptions mentioning that the listing was crafted with eBay Bundle Buddy. If you upgrade to Pro, all future and current bundles have 100% clean, unbranded descriptions with zero watermark.
Can I cancel my Pro subscription anytime?
Yes, absolutely. You can manage or cancel your subscription at any time with 1 click via the Stripe Customer Portal. If cancelled, you will retain Pro access until the end of your billing period, after which your account reverts to Starter.
