eBay Selenium + Email Script *NO API*

We have been using a script to purchase from eBay for the last 2 years which has finally become too outdated to function due to Selenium and google chrome updates. So we feel it would be better to start from scratch. I need a script which will run on a dedicated computer at all times that will be capable of the following. I am currently using a software that notifies me via email every time an out of stock item becomes available. sometimes there is 1 item in the email sometimes there can be up to 30 items. each item in the email has a "BuyItNow" hyper link that will take you to the ebay listing. ALL ITEMS NEED TO BE PURCHASED QUICK! All the email subject lines are uniform, what this script has to be able to do is 1. Click the email when it's received. 2. Open "BuyItNow" hyper links to open the available items. 3. Add all available items to the cart included max qty. (If 3 are available I want all 3) Or any other qty. [login to view URL] "No " to extended warranty 5. Go to Cart 6. Click credit card as payment method 6. Check out with the items. (The credit card and address are already entered in ebay's system) 7. Move on to the next item if applicable. This is a fairly easy script that will run on a dedicated computer. I need the check out time to be very quick as this is a highly competitive environment and any later the item will most likely be sold out.
