Here is quick inspiration how can auctions be done in the format of forum topic. Successful example how they can be organized is bitcointalk:
https://bitcointalk.org/index.php?topic=2273825.0
In that topic you’ll find auction for advertising “slots”. Just replace slot by seed pack for our purposes and BTC by USD:
Post your bids in this thread. Prices must be stated in BTC per slot. You must state the maximum number of slots you want. When the auction ends, the highest bidders will have their slots filled until all nine slots are filled.
So if someone bids for 9 slots @ 5 BTC and this is the highest bid, then he’ll get all 9 slots. If the two highest bids are 9 slots @ 4 BTC and 1 slot @ 5 BTC, then the first person will get 8 slots and the second person will get 1 slot.
The notation “2 @ 5” means 2 slots for 5 BTC each. Not 2 slots for 5 BTC total.
- When you post a bid, the bids in your previous posts are considered to be automatically canceled. You can put multiple bids in one post, however.
- All bid prices must be evenly divisible by 0.02.
- The bidding starts at 0.1.
- I will end the auction at an arbitrary time. Unless I say otherwise, I typically try to end auctions within a few days of 10 days from the time of this post, but unexpected circumstances may sometimes force me to end the auction anytime between 4 and 22 days from the start. I have a small bias toward ending auctions on Fridays, Sundays, and Mondays.
- If two people bid at the same price, the person who bid first will have his slots filled first.
- Bids are considered invalid and will be ignored if they do not specify both a price and a max quantity, or if they could not possibly win any slots
For our goal it could be easily adjusted and example offer for the auction would be:
Mr.Nice - G13 Haze: 1 pack @ $15
Hazeman Seeds - '88 G-13 / Hash Plant: 2 packs @ $25
Some basic rules for the auction should be stated by the seller in original post and should include:
- Starting bid amount
- Minimal bid increment
- End of auction (for creating event in multiple timezones use time zone converter)
- Specify items to sell
- Separate packs auctioned one-by-one or
- Whole package of multiple seed packs to sell as one item.
