What a great story! I do something like that but I take it to the crooks. I know my profession/drones and it's a hot topic right now. The thing is they almost all look the same but the prices can vary from $20, $200 to $2,000. It seems some folks have figured this out and have decided to take a used $50 item and try and sell it for 5 times that amount. When I see this I first double check my figures . Then I confront the person in a nice but forward manner. Ask them WHY they are selling the item for so much? After I have given them a chance, I post their answers. Which are usually quite rude. Along with that I post their add, their profile page and a screenshot of the item their trying to sell with 5 or 6 pricing options from vendors like Amazon, Wal-Mart and Best Buy. I never ask people in the add to buy from me instead. I just ask to please do your homework before purchases and don't give your money to crooks. I feel the scam artist are putting a black eye on Offer up as well as the hobby. Well, that's my story. I hope im not over stepping my boundaries but i cant just sit and watch innocent people get taken advantage of. God Bless everyone, even the Scammers.
