So here are some numbers ... and no doubt, an artist with a good selling shirt will be losing out the most. I don't see Woot being the one making out like the bandit either; the main advantage would be the consumer getting the shirt for 1/3rd off.
Some numbers for Poison ...
4700 * $10 = $47,000 total. $46,000 to Woot, $1,000 to artist.
4700 * $9 = $42,300 cost, so $3,700 profit.
Under the previous cap ...
3000 * $10 + 425 * $15 = $36,375 total. $35,525 to Woot, $1850 to the artist.
3425 * $9 = $30,825 cost, so $4,700 profit.
For Death ...
3000 * $10 + 200 * $15 = $33,000 total. $30,600 to Woot, $1400 to the artist.
3200 * 9 = $28,800 cost, so $1,800 profit.
Under the new cap ...
3800 * $10 = $38,000 total. $37,000 to Woot, $1,000 to the artist.
3800 * $9 = $34,200 cost, so $2,800 profit.
I factored that only 1/4 that would've bought at $10 vs. $15, and from the math that I've done in the past, a $9 cost for each shirt.
My take on this ... unless the payout is going to be raised for the artist, I don't like the new (higher) cap myself either. If Woot wants to keep selling later in the day, I'd much rather see a graduated payment system in place for debut day - first 3,000 at $10, then continue selling at $12 with the $1 commission. Woot yields more revenue, and the artist reaps a greater reward for a good selling design. Even if that artist happened to be draw bunguins ...
