Run in your JavaScript console: document.cookie = 'optimizelyBuckets=' + escape('{"145285685":"145865258"}') + '; domain=.23andme.com'; document.location.reload(true); The other values I found: 69 -> escape('{"145285685":"145818631"}') 99 -> escape('{"145285685":"145866265"}') 149 -> escape('{"145285685":"145285686"}') 299 -> escape('{"145285685":"145891045"}') Edit: Actually, it looks like this no longer works. They may have noticed and stopped the A/B test. You can empty the cart and run window.$.ajax({url:'/special_offer/49NOV2012/?json=true'}) Then click add to cart and once in your cart it will be $49. I'm going to have to start looking at more websites' Optimizely codes!
