Today only, A4C offers the used Samsung Gear S3 Classic Smartwatch for Verizon in Black for $129.95 with free shipping. That's tied with our mention from a month ago as the best deal we've seen. (It's $50 under the lowest price for a refurbished unit.) This smartwatch features an Exynos7270 1GHz dual-core processor, 1.3" 360x360 super AMOLED touchscreen with Gorilla Glass SR+, and heart rate monitor. No warranty information is provided, but it is covered by an A4C 30-day "just because" return policy.
Frugal isn't smart if you put off replacing these things. Waiting too long can cost money or even endanger your health.
