Honestly, I'm not a big fan. But I think it's cleaner if the markup price is still great value. If the re-seller is prepared to go to the trouble of paying and collecting the goods, and then re-advertising them at a good price then they deserve the profit. Especially if they are flexible in terms of delivery, like offering to meet you somewhere in-between, or a few different locations. That can make the deal more accessible to someone who may not have wanted to risk buying from someone far away. Also, re sellers that have credibility (because they do this sort of thing a lot) reduce the risk because they've checked the parts and give them their stamp of approval. I think the spirit of the thing is what counts. You can make a reasonable profit and have integrity and care for others too.
