Pssst is a General Mills program that you can join to try new GM products and get coupons before they are widely released to the general public. I have been able to try many yummy products through this program. Just click on this link to sign up.
While on the site, check out MyGetTogether. It's a new party program, similar to HouseParty, where you will be able to sign up to host General Mills parties and get to try products and new recipes. This is a brand new program that Pssst and General Mills are launching, so I'm not exactly sure how the site will work, but it sounds fun!
On pssst.generalmills.com, you will see a tab with detailed information on MyGetTogether.
