How fast do you think these will go? There's 470 of the 10K ones so basically you need to be among the first 100 or so people if you want 5 sets.
I have a feeling this will end up like when they used to do this with electronics where there was one deal a day and it was first come first serve. Everyday I went hoping to score a thousand dollar electronic item I didn't need for $300 and everyday I left empty handed.
I can't even remember who used to run that promotion, but I think it was AMEX then too.
