What is Comic Bundle Finder?

Let's say you're trying to complete a run and you need a handful of random filler issues. You've tried cons, you've tried your LCS, but no one has that Amazing Spider-Man #327 (1989) or Daredevil #246 (1987) that you need. You can find them on eBay for a couple bucks, but each seller is charging $8 shipping. If you need five issues, you're looking at spending $50 for $10 worth of books.

Most sellers will bundle shipping at a much cheaper rate than buying issues individually. Comic Bundle Finder searches eBay for the issues on your want list and identifies sellers who carry multiple issues you need. That way you can buy several issues from one seller and save on shipping.

Doesn't eBay already have this feature?

No. Well...yeah, no, not really. You can go to ebay.com and search each item on your list, click the first listing, click "Seller's other items", and search through their inventory for each of the other issues, one by one. Then you move on to the next listing. And the next one. But this is tedious, frustrating, and a waste of time.

If you play any trading card games like Pokemon or Magic: The Gathering, you might be familiar with TCGplayer's cart optimization tools, which are similar to what CBF does. TCGplayer is owned by eBay, but for whatever reason the functionality doesn't exist on eBay.

How do I use it?

Paste your want list into the text box on the home page — one issue per line — then click Find Bundle Deals. The tool searches eBay for each issue and groups results by seller. Only sellers with 2 or more of your issues appear in the results, unless you specifically search for one single issue, in which case only sellers with 2 or more copies will appear.

What file formats can I upload?

The tool accepts three formats:

• League of Comic Geeks (.xlsx) — export your wish list from your profile page
• CLZ Comics (.csv) — export your want list from the CLZ app
• Plain Excel (.xlsx), comma-separated values (.csv), text (.txt) — one issue title per line

Why are some issues missing from the results?

A few possible reasons:

• No active eBay listings matched that issue title
• The issue title format didn't match eBay's listings closely enough — try adjusting the title (e.g. removing the year, or shortening the series name)
• No seller has that issue plus any of the others in your list

Are the eBay links affiliate links?

Yes, links to eBay listings use the eBay Partner Network. If you buy through a link, we may earn a small commission at no extra cost to you. This helps keep the site running.

Premium Features

Do I need an account to search?

Nope. Basic searching is free and works without signing in. An account is only needed for Premium features.

What files can I upload?

If you use League of Comic Geeks or CLZ, you can export your collection and upload the file here. Both sites keep your collection and your want list in one file, which we can use to populate your searches or to analyze for collection gaps.

You can also upload a plain .xlsx, .csv, or .txt file with one issue per line. It works best if you format the issue as "[Series Name] [Issue Number] [Publication Year]".

What does the Gap Analyzer do?

It will run through your collection list and check for gaps of a certain size (default is 5). For example, if you have issues #3, #5, and #9-11 of a 20-issue series, it will detect that you are missing issues #1-2, #4, and #6-8. It will detect leading gaps (issues #1-2) because every series starts with #1 (well, almost every series), but it won't detect issues #12-20, because it's only trying to fill gaps and a series could be infinitely long.

Can I cancel anytime?

Yes. Cancel from your account page and you keep Premium access until the end of your billing period. No questions asked.

What’s the difference between monthly and annual?

Same features either way — annual is just $36 upfront instead of $5/month, which works out to $3/month. You save $24 over the year.
