That doesn't make much sense to me. The purpose black friday sales for companies seems to be 1.) to drive customers to their store where they will also buy non-sale items and 2.) to build brand image and name recognition with potential customers. Neither of these objectives are met by selling to scalpers.

yeah, but whats the fun in that.

As far as captcha, for the use case of just running on a local computer to buy one thing you could have it feed the user the captcha to solve over and over.

They are a bit expensive couple hundred bucks to license. Got any favorite communities?
