7 products in Smart Home & Security were reported in stock at $20 or less in the Houston, TX area as of Oct 22, 2026, 5:14 PM CDT, from $13.99. Prices and availability are as reported by each retailer.

> Availability is reported by each retailer and checked by Aisles about once a day. Each listing is verified against that store’s own inventory record, and anything not re-checked within the freshness window is shown as unknown, never as in stock. It is a check of the store’s system, not an in-person shelf count, so stock can sell out after the check.
