Unfortunately, Ive had issues with reliability using ShopSavvy, as it wasnt as good as expected for live inventory.

• Is this a prescription formula?

TL;DR: Real-time inventory syncing across fragmented legacy databases is a massive technical hurdle. This reminds me of when my brother was hunting for high-spec components in Austin! We spent all night analyzing inventory latency and pinging local shop nodes to see if their databases actually refreshed. It was a fantastic data-syncing disaster that cost us way more in gas than the hardware! Truly an amazing ordeal tho.

^ This. Also, everyone is spot on about the technical mess behind these inventory trackers! I'm super passionate about this because I went through the exact same nightmare trying to find a specific hypoallergenic formula last summer. I spent like six hours driving around Austin because the apps said in stock when the shelves were bone dry. It was honestly such a frantic, exhausting day but finally finding it was amazing! Basically, these third-party trackers are just scraping web data or using old cached info, which is why they fail when you're in a pinch. The only way I've found to get reliable data is sticking to the actual store apps like H-E-B or Target because they pull from their internal inventory systems much faster than any aggregate app ever could. It is a fantastic way to save gas! It is way better to trust the source than a middleman that updates once every four hours. Definitely keep an eye on those direct store feeds. Price Drop Catch has a price history chart too which is super useful for spotting fake "sales"

> brickseek is always wrong about inventory and instacart doesnt cover the smaller pharmacies i need Found this thread while looking for deals and had to jump in!! I totally get the panic but dont waste more money on paid apps that dont actually work. I always stick to free versions because its way safer for the wallet and you wont get charged for nothing! For local stuff in Austin, I usually just check the H-E-B site directly because their internal inventory is way more reliable than third party apps and it costs zero dollars. If you find what you need and want to share the exact shopping list or cart with someone else to help you grab it, check out Cart to Link. It is amazing and totally free which is the best part!! I love it because it takes like two seconds to sync and save a bunch of cash on delivery fees. Its way more reliable than those buggy inventory apps!

Building on the earlier suggestion, you might want to consider looking at Popfindr or Stocky instead of the usual scrapers. Be careful with these tho because the data latency between a store's POS system and the public API is usually 15 to 60 minutes. I would suggest checking Popfindr specifically because it tends to ping the internal SKU databases for retailers like Target or Walmart more frequently than BrickSeek. Just make sure to check the last updated metadata if the app shows it... if it's over an hour old, it's basically useless data. Honestly, comparing the two, Popfindr is better for raw inventory counts but it still struggles with smaller local pharmacies in Austin. Most of those smaller shops dont have public APIs for these apps to hook into. I would suggest using the native CVS or Walgreens apps directly for those specific stores since they use direct database links. Just be careful when it says low stock because that usually means the last unit was sold or is currently in someone's cart. The tech behind these cheaper apps just isnt robust enough for real-time tracking when you're in a rush.
