About Bonavendi
Sell used books, media & electronics for more — or buy them for less. Bonavendi compares prices across dozens of professional vendors in seconds. Free to use.
You wouldn’t accept a supermarket where the same product costs $2 at one register and $6 at another. In re-commerce, that’s normal — prices for the same item vary by 200-500% across vendors. Bonavendi is the price comparison for used books, media and electronics. One search, multiple offers, you pick.
What Bonavendi Does
Selling? Enter the ISBN or EAN, and we check what multiple professional buyers will pay. Instead of going to one vendor blind, you see who pays most — in seconds.
Buying used? We compare prices across vendors so you find the cheapest offer without opening ten tabs.
Either way: more money in your pocket, less time wasted.
Why Comparing Pays Off
Prices for the same item vary dramatically across vendors — often by 2 to 5 times. An example:
| Vendor | Price for the same book |
|---|---|
| Vendor A | $1.50 |
| Vendor B | $3.20 |
| Vendor C | $6.00 |
Without comparing, you might sell to Vendor A and leave $4.50 on the table. With 20 books, that’s $50+ difference.
The same applies when buying: the cheapest vendor for one title may be the most expensive for another.
Smart Allocation: More Money Through Clever Splitting
When selling, Bonavendi doesn’t just show you the best price per item — it calculates the most profitable split across vendors.
Why this matters: Which vendor pays most for a given item is unpredictable. One vendor offers $3 for a book today, $1.50 tomorrow — because they have enough copies. Another vendor wants exactly that book and pays $5. A different vendor wins for every item.
What we do: Bonavendi checks each item, finds the best price, and calculates the optimal allocation — factoring in shipping costs and minimum order values.
The result: The best price compared to selling everything to one vendor. For a cart of 30 items, that can mean $20-40 extra.

Professional Vendors, Fixed Prices
We compare professional vendors who give you a binding price before you ship. No surprises.
This is different from:
- Auctions (eBay) — you don’t know what you’ll get
- Classifieds — messaging, haggling, organizing pickup
- Flea markets — weather, booth fees, unpredictable outcome
With professional vendors: accept the price, ship the package, money in your account. Usually within a few days.
How Selling Works
- Enter your item — ISBN, EAN or scan barcode
- Compare prices — Multiple offers at a glance
- Go to the vendor — One click to your chosen partner
- Ship — Usually free with a provided shipping label
- Get paid — Payout after review (1-5 business days)
The transaction runs through the vendor directly. Bonavendi connects you — your items never go through us.
How We Make Money
Bonavendi is free for users. We earn a commission from vendors when you sell or buy through our links. That’s why the service is free.
Over 10 Years of Price Data
Bonavendi has been running since 2012. Over 20 million price comparisons and counting. In that time we’ve:
- Added dozens of vendors
- Made price queries faster and more reliable
- Built and optimized the smart allocation algorithm
- Expanded from books to media and electronics
We’re a small team that has been building this for over a decade. We believe that a more circular economy — where things get reused instead of thrown away — is better for everyone. Price comparison makes that easier by removing the friction from resale.
