I usually don't post in the OTT, but someone told me about the Pepsi stuff, so I'd figure I'd just share my method at getting it done real quickly. If you're wondering what my typing speed is, it's about 60 wpm (probably slower than many CAGs).
Right, open your PepsiStuff account in Firefox and just let it sit there.
Open Notepad
Open Internet Explorer, go to Internet Options > Privacy > Sites and block pepsiusa.com. Make sure to turn off that annoying music
Enter a random email and then enter the captcha and copy the code to Notepad
Go back IE and add a letter to anywhere in the email, hit submit and it will give you a new captcha. Enter the new one and it'll give you a new code.
Keep doing that until you're ready to enter the codes in Firefox
You don't need to refresh IE at all or open new tabs. So far it's been the fastest way for me to get points. Also, am I the only one that's gotten ten point codes every once in a while?
