Huh?
The last two sold boxes that I see on eBay (which were the only two in the last few days) sold for $2350 and $2450.
There is also a Buy-It-Now or Best Offer listed at $2525, so at best - $2450 is the current eBay price.
On a $2450 sale price, eBay fees are $147- $245, PayPal fees are a bit over $66 and shipping costs are around $50.
I don't have a Masters in Mathematics, but I think that nets you $2,187 - $2,089.
