The store locator supports unlimited searches per day. We don't restrict the searches per day as no one likes to have limits.
On the other hand, your map provider offers only a fixed number of map loads and searches per day and per month. What does it mean?
It means that both Google Maps and Mapbox (the map providers that our store locator supports) offer a monthly "free tier" that allows you to use the provider without paying anything extra. Only for higher traffic websites, the "free tier" won't be enough (especially with Google Maps) and they'll charge additional requests. Unless you have high traffic, you won't probably pay anything additional.
Please note: this is not related to StoreRocket and it applies to all websites using Google Maps and Mapbox.
