On the DIY site, some of the ingredient sources have a letter ‘S’ next to them. What does that mean?
I’ve only ever seen @QuidNYC do this, but here’s his explanation (which you can find in the overview of some of his recipes):
Amazon Subscribe & Save:
The ingredients designated “Amazon (S)” are eligible for Amazon’s Subscribe & Save program. I have sought to configure the rate of consumption for each of these ingredients to be consistent with periodic ordering of either one or two units per two-month period. Taken together, these ingredients meet or exceed Amazon’s five-item threshold for a 15% discount (all Subscribe & Save items should be arranged to ship in the same bimonthly cycle).
Thanks for the reply!
