I'm sure that as a dedicated forum user and BPL member, you wouldn't intentionally try to scam anyone by selling a lightly used item significantly higher than the purchase price. That is certainly not something the people I've met on BPL would want to do, so I'm readily willing to give you the benefit of the doubt and say it was an honest mistake.
I was interested in the item you had for sale and so, naturally, I looked up the amazon price to see how good a deal I would get and how much I would save by buying the item used. This is something anyone making such a purchase would likely do and they would readily find the same information as I did.
Because you obviously have no intent to cheat anyone and because nobody is likely to purchase the item so far over the market price, I wanted to let you know this information so you can correct it and save yourself a whole bunch of wasted time. My intent was to help you sell the unwanted item, not to interfere with your sale, which I'm sure had only the most honest intentions.
If, by any freak chance, you were aware of the discrepancy I pointed out, then I make no apologies.
