Right now over at Amazon you can get Cascade Rinse Aid Dishwasher Rinse Agent, Original Scent, 30.5-Fluid Ounce for $6.62 (reg. $15.01) when you choose subscribe & save.
This is one of those items I ALWAYS forget to buy at the store and seriously hate to make a trip just for this. Love grabbing it online and taking it off my list – and it is amazing on my dishes.
Once your item ships you can click through to “my account” from your email – choose “my subscribe & save items” and cancel the subscription so it won’t ship again at a higher rate.
