-Thanks for subscribing! You'll hear from us here whenever we've got something
-worth sharing.
+Thanks for signing up. Here's what you can expect from us: notes on new batches, honest word when something's running low or out, and the occasional look at how a bar actually gets made.
 
-Talk soon.
+Every bar we sell is cold-processed by hand, in small batches, and cured for six weeks before it ever reaches you. We keep the ingredient lists short and recognizable — things like rolled oats, French green clay, activated charcoal, oat milk, local honey, and shea butter, not a wall of things you'd need to look up.
+
+Right now the lineup is:
+
+- **Lavender Oatmeal Bar** — $8, gentle enough for every day
+- **Clay & Charcoal Mint Bar** — $9, running low
+- **Oat Milk & Honey Bar** — $8, unscented and mild
+- **Cedar & Sage Bar** — $9, currently out while we cure the next batch
+
+If something's out, we'll tell you rather than let you guess — that's the whole point of this list.
+
+Talk soon,
+Matthew & Marisol
