Hey pals! Before asking me about something you're missing, check the bundle site itself to make sure it's me and not them. GoGoBundle is a frequent offender of this, they seem to be adding/removing items all the time after we do our initial scrape of the bundle page.
Also as reminder, the items on group buy pages are fetched using an automated process and are in no way guaranteed to be accurate. Think of it as an extra convienence feature rather than a sure thing.
