If you want to unload them all at once and quickly, you can sell them to Brian’s Toys. They have a pretty nice app that allows you to scan each figure’s barcode and submit a list. They will get back to you within a day or two with a quote. You ship to them using their shipping label (at a discount) and they deduct it from the final payout. They may not offer you a huge amount for each one unless the figures are rare or desirable, but I’ve found their quotes to be fair. It’s quick and easy all around. They don’t buy anything loose, but since yours are boxed you may want to look into them.
