So you're going to send somebody 20 euro in btc , plus the fees (have you checked them lately?) even before they buy you that thing whatever it is?

If you would have said you're offering 30-50 euros for this you would have already got a lot of offers but that 280 euros for a harmless purchase just raises red flags. No wonder everyone is starting to get suspicious, and they should do so, in the best case scenario you're just trolling.

That being said I must admit I'm so damn curious what's behind all this.
