Bonanza vs eBay: can the same listing sell on both?

The short answer, by what you need

List on eBay when one listing has to reach the most buyers. Add Bonanza as a second outlet for a listing you already have, because the title, the category and most of the details carry over with little rewriting.

Neither marketplace is better for every item. The table sorts the common cases by what each one publishes about itself, and the fees on the same sale are worked out further down.

One item, two listings: what carries over

Take a vintage Pyrex mixing bowl. The title "Vintage Pyrex 403 Mixing Bowl 2.5 Qt Butterprint Turquoise on White" is 67 characters, so it fits both marketplaces unchanged. Bonanza's listing API calls the title "maximum of 80 characters" and says an item can't go up for sale until it has a valid one. eBay's Seller Center says you have 80 characters and to use as many as you can.

The details move just as directly. eBay's item specifics and Bonanza's item traits are both a label and a value, such as Brand: Pyrex or Condition: Used, and each marketplace offers its own set per category. Bonanza says specifying traits "will mean more traffic for the item", on Bonanza and from search engines. The description is the one field with room to spare on Bonanza: up to 60,000 characters, with most kinds of HTML allowed.

How each one searches

Bonanza's search API sorts by Best Match by default, which it says is based on community buying activity and other relevance factors. A keyword query searches item titles only by default, and Bonanza checks the words in context with each other. That is the search Bonanza documents for developers. It doesn't say whether its website search reads the same fields, but it is the only description of Bonanza search we can read, and it puts the title first.

eBay's Best Match weighs more than the words: how closely the listing matches the search, how popular the item is, the price, the listing's quality and completeness, the return policy and handling time, and the seller's track record, eBay's help says. On both, the details do a second job as filters.

• Bonanza: item traits "can be applied as filters to narrow down search results", its API documentation says.
• eBay: buyers filter search results by item specifics, and a listing only appears in a filtered search if it has the matching specific.
• So on both, an empty detail can drop the item out of a filtered search, however good the title is.
• Neither publishes a weighting you can write to. Write the title as the search a buyer would run, and fill every detail you actually know.

What each one charges on the same sale

Both charge mostly when an item sells, and Bonanza takes less of a typical sale. Bonanza's final value fee is at least 11% of the Final Offer Value, which is the price plus only the part of the shipping above $10, never less than $0.50, plus a $0.25 transaction fee for a seller without a membership (Bonanza's pricing article, read in a browser on 25 October 2026). eBay's is 13.6% of the total amount of the sale in most categories, shipping included, plus $0.30 an order of $10 or less and $0.40 above (eBay's selling fees page, read 24 October 2026).

On a $40 item with $6 of shipping, that is $4.65 on Bonanza and $6.66 on eBay, our calculation for a US seller with no ads and no Bonanza membership. Part of the gap is the rate and part is the shipping: the $6 is under Bonanza's $10 line, so none of it is in Bonanza's base, while eBay charges its rate on all of it.

• Bonanza's 11% is a floor you can raise: its advertising is opt-in, at 11% to 30% of the Final Offer Value, and the level you pick replaces the base rate.
• Bonanza charges a one-time $14.99 set-up fee to a new seller, and $0.03 a month for each active listing above 50, at most $20 a month.
• eBay gives 250 zero insertion fee listings a month, and more with an eBay Store.
• Above $4,000 of Final Offer Value, Bonanza charges a flat 1.5% on the rest. eBay's rate drops to 2.35% above $7,500 an item.

Selling on both without selling one item twice

Bonanza is a separate company, so the two listings don't know about each other. When the item sells on one, end or update it on the other the same day. That is our advice, not a rule of either marketplace, and it is the step that keeps a one-off vintage piece from selling twice.

The other line not to cross is eBay's. If you offer or ask for contact details to buy or sell outside eBay, eBay charges its final value fee even if the item doesn't sell, its selling fees page says. So never point an eBay buyer to your Bonanza listing.

What Sellura does here, and what it doesn't

Describe the item once, in a few words or a photo, and Sellura writes the Bonanza listing to Bonanza's own limits: a title of about 75 characters inside the 80, up to 8 item traits as short name and value lines using only details you gave, a plain-text description that opens with what the item is and its condition, and 10 search phrases of up to 30 characters to work into those fields. The 75, the 8 traits and the 10 phrases are our numbers, not Bonanza's. Switch the marketplace to eBay and the same item comes back with a title inside eBay's 80 characters and 8 item specifics.

The title preview and a 0–100 score are free on every generation, no card. The score is deterministic: the same listing always gets the same number, and each weak factor comes with one fix written for that listing. The finished listing costs 1 credit, and the first unlock is free on a new account. Starter is $15 a month for 25 credits or $150 a year, and Pro is $24 a month for 65 credits plus bulk, or $240 a year.

• To check a Bonanza listing you already have, paste its title and description into the checker above. Sellura doesn't grade Bonanza links, because a listing page loads the seller's description separately.
• Sellura doesn't post to Bonanza or eBay, sync stock between them, read either marketplace's search or track where a listing ranks.
• It has no research database, no sales data and no ads analysis.
