SafeRates: USPS Shipping Rates uygulamasına genel bakış
Live USPS rates, no carrier account
Up to 3 services with delivery days
Default weight for items without one
Backup rate if the feed is down
Live USPS rates at checkout, with no carrier account to open and nothing to configure at the carrier. Rates use the address and weights checkout sends, shipping from your site's business address.
Turn SafeRates on for your US shipping region after you install it: Settings → Shipping, delivery & fulfillment, open the region, choose Manage apps, turn SafeRates on and save. Until it is on, checkout never asks for a rate.
If your store already has a free or flat shipping rule, that rule stays available and can be selected first. Turn it off or limit it if you want customers to see only the USPS options.
Every quote returns up to three USPS services, each with a delivery estimate beside its price, and an optional handling fee is included in what shoppers see. A default weight and a backup flat rate are optional: without one, a cart with a weightless product gets no option; the backup rate keeps one on screen when the live feed fails. Overview lists every rate request with its result, response time and default-weight use.
SafeRates returns USPS services only. It does not connect your carrier account, include negotiated discounts, buy labels, or handle international shipping.
