there is a website called who offer discount items every Tuesday, and Thursday from 11am to 4pm PST. it's called outrageous deal. for now I setup my firefox to refresh every seconds and when the item is posted I buy it, but it doesn't work all the time, the item can be posted while my webpage is refreshing, and somebody else get the deal. I am wondering there is something that can be done, as soon as the item is posted (maybe based on Item number and price) it trigger the buy now button.
Please contact me for more information.
