To get samples of Cascade Platinum Plus pods simply log in or create an account with P&g here. Once your logged in go to their promotional page here. The request form online will look like this, fill it out and submit.. Their samples arrive within 4 to 6 weeks.
These Cascade samples are from P&G, they do send them out, I can confirm that I have received several household product samples by mail from them already and on several occasions their products came with high value manufacturer coupons.
