Summary

Integrates average eBay prices for comparison into Facebook Marketplace and Craigslist. Stop trying to decide if the item is reasonably priced and let this extension do the work. Craigslist Deal Finder provides average prices found on eBay for each item on the page.

A list of the found eBay items can then be displayed by clicking the "eBay Price" button. This will display all the retrieved items and link them to the associated eBay web page.

If you're not getting the results you expect open up the search filter panel and modify it to fit your use case.

User reviews
The extension is very bare - bones. Only a couple options and a lot of the data is just incorrect. The only price the items should be compared against is the sold items price. Meaning the price people are willing to pay for the item. It doesn't look like this extension can get that data. I'm surprised it took anyone this long to make an extension like this and it's a good start but they have a long ways to go. I'll check in periodically and increase the rating if the extension improves.

Awesome, this honestly has given me some side income. Can you write code that will drive around and pick up the FB marketplace items now?
