Buy Cheap on Forum then Sell for Profit on TradeMe

[longshot]

All of what I list here is stuff I just don't need any more, it is taking up too much space or that would be more use in someone elses hunting setup. I give away a fair bit of stuff and often ship it for free too if it has no real money value but is too good to throw away, usually stuff you can't buy anymore but that someone out there will want (like a single scope ring).
Often if I can't remember what I originally paid for something, I just put a low price on it to move it on quickly. I do also put normal prices on stuff that I like but don't need.
I often sell stuff on TM too, but good stuff I prefer to sell here.
Ultimately I think that my material contributions to the forum carry a degree of goodwill and that is in acknowledgement of what a resource the community is to me.

Some time ago I was selling a scope, it was a nice one, something that would be recommended within the first few posts of a 'what scope should I buy' thread. But it was also a little bit rare, no longer produced, it was just a little bit special, something I thought someone from here would appreciate. The buyer asked for a discount which I conceded to. A few days after sending it, I saw it on TM. Alongside something else I had given away for free with free shipping.

I was disapointed but I recognised as many people on here have pointed out that I put no contract on the buyer not to do this.
The bitter pill was that I have been looking for a good deal on a rangefinder on behalf of a mate who could use one but can't afford one, when I saw one here that I would have bought, it had already been snapped up and it was on TM a few days later with a >100% mark up. It was the same person that bought the scope to on sell.

My point is that if you do it a bit here and there, especially buying something broken, fixing it and selling it, fair enough. But if someone made it their full time job to just mine the BuySellSwap for bargains, then it reduces it to a place without any bargains and ultimately to a place without any goodwill.

Anyone capable of listing something here can list it on trademe instead if they choose to, I don't need someone else to do it for me and take a substantial cut in the process.
