Whenever i have some time off i tend to go to local flea markets and garage sales to check out what kind of retro goodness people have for sale. It happens quite often that i find people who are selling things far below it's actual value. This happens most of often when kids/families have a stand. They either go by eBay prices or lower than that. This only becomes a problematic situation when they aren't actually aware of what they have. Children are usually not well-versed in these matters and sell items like a GBA SP AGS-101 and GameBoy Micros among other things for ridiculously low prices. I know that some people bank on things like these and take advantage of such situations. I personally find that despicable. Especially re-sellers are known to behave shamelessly like that. We should treat each other fairly and ethically when dealing with one another and not try to make a quick buck off of someones lack of knowledge. Whenever i find something like that and am interested in purchasing it, i explain to them in detail what they are actually selling there and then make them a fair offer. People usually respond very positively to it and one kid was so happy that he gave me a handful of GameBoy games just because i didn't try to rip them off. Retro-collecting should be about the passion for gaming, not about profit. Tl/dr: Stop ripping off kids.
