I don't know if that user was asking the question in context of collaboration with the app (despite posting in this topic). I was just answering from a general POV. Even with the app, if you're just looking for steals, you're unlikely to have gained momentum from a time/cost perspective. "No amount of money ever bought a second of time."
It would be nice if, y'know, people joined the hobby out of passion for the hobby. The less money-hungry vultures - the better it is for the hobby. Concur? That's not a dig on dealers, either. There will always be those who are in it from a business perspective, but there are too many people who think they can sneak right past ya for a profit and it simply hurts the circulation of product among the people that actually want the product. Good, reputable, dealers are good for the hobby in moderation.
