That is a cool approach

I just have a missing link, I will figure out somehow. There is a bunch of affiliate network, which has deals with websites, find some websites with outlet bikes. Then, its seems like I can follow your approach for this.
I just need to figure out the link between, im posting on:
- facebook marketplace
- letgo
- and so on..
And then you get a contact with a person who wants to buy the item. Normally when im selling my old crap, I would just get in contact with a person, and he will bring the money and come and collect the item.
But you have the approach of having a landing page in between. In some way you have a smart approach to bring the lead to your landing page.
It just seems really scammy to me to answer something like:
Hi,
Thanks for the interest in my [xxxx], you can checkout the item at my [website]. But, I cannot really come up with better ideas, so it must be how you work, its really a nice approach, which can easily be copied.
Great inspiration, thanks, good luck.. If you would need any automation tools for your work, feel free to reach out, otherwise ill properly play along.
