Mike Leonard wrote in to suggest using Backpack to offer supplemental information when selling items on Kijiji, eBay, Craigslist, etc.
I use Backpack as a supplemental information page when selling items on [classifieds site] Kijiji.I set up my ad and include a link back to my Backpack page, which has been publicly shared.
Instead of the standard 4 images allowed i can display as many pictures and very detailed descriptions as needed for the item I am selling. It has helped significantly when selling higher end items where people want to see more detail than is offered in the standard Kijiji ad.
The best part about it (as you know) is how fast you can get the page up and running.
Here's an example: Mike's page that offers details on a Sharp 26" LCD Television for sale.
Have a tip for other 37signals customers? Let us know.
