We do the subscribe and save also. Have for about a year now. The more items you do, the more you save.
We don't do a lot, and have it set for every 3 months, and usually 2, maybe 3 different items.
It's a way to help stock up. We get a couple 500 count aspirins, some suave soap, maybe a 3 pack of tea bags. Go 2-3 shipments like that, then change things around. Add to, drop, reduce, etc
