You must be joking abut 25%-30% commission. Gunbroker only charges 3%-5% depending on sale amount, and it is regressive. On a $1,500 sale the commission is under 4% at $58.75.
I buy and sell quite a bit on Gunbroker as an FFL. Here are some best practices:
1. Provide lots of high quality pictures (30-50) with details of all imperfections and write a detailed description. People appreciate honesty.
2. Schedule the auction to start/finish at popular time. The best is Sunday 8-10 PM Eastern. I run 14-day auctions and start/finish at 9 PM Eastern on Sunday. Best dime you can spend on Gunbroker is the 10 cents it costs to schedule a listing.
3. Pay the $2.95 to put your listing in the too 10% of “featured” listings.
4. Provide a phone number so people can reach out with questions or at least answer email questions quickly. Nothing people hate more than an anonymous seller who doesn’t respond. Making yourself real also alleviates buyers’ concerns that you are a scammer.
5. Auctions that are listed by people with A+ rating and a large number of feedback comments do the best. If you are new, you can either be diligent and build up feedback, or if you do not plan to sell on Gunbroker often, you may be better off consigning to an online seller with an FFL such as myself or others on this forum.
Now for the really big question - pricing. I run all my auctions as penny-start no-reserve. In 99% of cases I do better than starting close to a number I want. I describe it as “monkey see, monkey do” psychology. People will bid when they see others bid. If you are too risk averse, start at a reasonable low number (maybe $1,000 for this Python) that will still generate bids. Putting it at $1,500 may or not not get a bid, especially because there are so many other Pythons. Last but not least, whatever you do, avoid setting a reserve. Not only will you pay extra 2% if you sell, but reserve turns off a lot of buyers.
