So, I have about 100,000 mailing stamps, and am looking to sell on the black market. Only problem is, I'm not too sure what website I can sell it on, where I can become a vendor, what the best place to go is. I am selling it much cheaper than its actual value. If this is not the right subreddit, it'll be great if someone can direct me to the right one.
Also, is there a market on the black for stamps? Are there any current sellers of stamps?
Be weary vendors. Refer to rule #17 - If it's too good to be true, then it probably is.
