If you missed out on last week's free 6-pack of TouchPad apps, HP just introduced another 6-pack including four new apps as well as two from the last 6-pack. The apps including the free promo codes are listed below:

This group expires on 10/1/11 or until the promo codes last, whichever comes first. Given that the last group expired in less than 5 days I wouldn't wait if you want any of these. To redeem the codes you need to use your TouchPad and have credit card purchasing enabled for the HP App Catalog. Enter the codes listed in bold above during checkout. Just like last time, these codes are only valid for US customers.
