## Common Customer Questions

**"What's the difference between bases and powders?"**
Bases are squeezable pastes that blend in cool water (stays fresh 10 days). Powders whisk instantly (no blender). Bases give more control over creaminess; powders are faster.

**"Can I use these for more than milk?"**
Yes — bases work as plant butter for drizzling. All products work in smoothies, baking, oatmeal, soups. Creamers go in coffee, tea, shakes.

**"How long stays fresh?"**
Unopened: shelf-stable indefinitely. Blended bases: ~10 days refrigerated. Creamers/powders: fresh indefinitely after opening (no refrigeration).

**"Is subscription worth it?"**
18% off + 2.5% cash back + free shipping make subscriptions significantly cheaper. No commitment; cancel anytime.
