In my town, there's a members' gear swap at REI tomorrow, and I've got a table set up to sell some gear. All items are in excellent condition, but it's not like the tags are still on. The items are used, but show no discernible wear.

A thread from several years ago addressed the "how to price" question; some replies were in the context of yard sales, citing lowball offers from unsophisticated buyers. I expect a more informed clientele tomorrow.

The biggest ticket items I have are a couple goose down bags. As I said, they're in excellent shape, but just not what I want anymore. If the most similar new bag sells for $X, is pricing at 50% of $X a good starting point? If I want it gone by the end of the swap, what % of new am I likely going to have to accept? Or is thinking in % terms not the way to go?

Thanks
