+## Reddit — March 26 Posts
+

+
+### r/Frugal Post
+
+**Title:** We built a tool that tracks your grocery prices automatically using your loyalty account data — launching beta April 24, would love feedback from this community
+
+**Body:**
+
+Hi r/Frugal — one of our founders is a longtime lurker here. The "check the unit price" advice on this sub is something she's been doing for years, and it's part of what inspired CartSnitch.
+
+We've been building CartSnitch for about a year. Here's the problem it solves:
+
+Your grocery bill has gone up — a lot. But it's hard to prove exactly how much, because:
+
+1. You don't remember what you paid 6 months ago for specific items
+2. Shrinkflation means prices can look flat while you get less product
+3. Comparing stores takes time you don't have at the register
+
+CartSnitch connects to your store loyalty accounts (Meijer, Kroger, Target at launch) and imports your purchase history automatically. No barcode scanning, no receipt photos. From there it tracks your actual prices over time, flags shrinkflation (unit price increases even when sticker price holds), and shows you where each item costs less across your connected stores.
+
+We're launching public beta on April 24. It's free — no subscription.
+
+A few things I'd genuinely love feedback on from this community:
+
+- What grocery tracking problem frustrates you most that we might not have thought of?
+- Are there stores you'd prioritize adding beyond Meijer/Kroger/Target?
+- Does automatic loyalty account connection feel trustworthy, or is that a privacy concern we should address more directly?
+
+Happy to answer questions about how it works.
+
+(Disclosing: I work on CartSnitch. Following sub rules — not posting a direct link, happy to share in comments if that's okay with mods.)
+
+---
+
+### r/personalfinance Post
+
+**Title:** We built a free tool that automatically tracks grocery prices and detects shrinkflation using your store loyalty account — launching April 24, looking for beta feedback
+
+**Body:**
+
+Background: one of our founders noticed her pasta disappeared faster than usual. Checked the box — it had gone from 16 oz to 13.25 oz. Price had barely moved. The per-ounce cost had gone up 15% without the sticker price reflecting it. Classic shrinkflation.
+
+We couldn't find a tool that tracked this automatically, so we built one.
+
+**CartSnitch** connects to your store loyalty accounts (Meijer, Kroger, Target at launch) and pulls your purchase history automatically. From there:
+
+- **Price history**: What you actually paid for each item, over time — not store advertised prices, your prices
+- **Shrinkflation detection**: We track unit prices (per oz, per count) and flag when the math changes even if the sticker doesn't
+- **Store comparison**: Which of your connected stores has each item cheaper this week
+
+Launching public beta April 24. Free. No subscription.
+
+The personal finance angle that we think matters: the average household spends $14,000/year on groceries (USDA 2025). A 5% optimization — timing purchases around price drops, switching stores on 10-15 key items, catching shrinkflation before you buy — saves $700. That's real money, and right now most people are flying blind.
+
+Questions welcome. (Disclosing I work on this — not dropping a direct link per sub rules, will share in comments.)
