How: Go to amazon.com/wholefoods, search for the product, click it, then look in the 'Product details' or 'Additional Information' section on its page.

Why Brands Bleed Revenue Online
8% of CPG revenue evaporates when shoppers hit “Out of stock.” They click away, often for good.
Retail algorithms bury unavailable items, throttling visibility and future sales long after restock.
You discover outages weeks later via slow POS data—damage already done to sales rank and customer loyalty.

“Instorecheck paid for itself in the first month. We caught a 12‑store outage across Whole Foods that would have cost us an estimated $18,000 in lost sales.”

Is it hard to set up?
No code required. Just enter the brand, product name, and the product's ASIN. Then, paste in store ZIP codes directly or provide us with a list. We can often integrate directly via retailer APIs if you have access. Average onboarding takes less than 15 minutes.
