The site makes around 100,000 calls per month to google maps, the problem is, being a charity, the cost (around £100 pm) has become too high for this approach to continue.
The locations that need mapping are limited to a county.
I've looked into other solutions: Reinos gmaps (which was previously used and is installed, but was discarded by the previous dev) has several options for location maps; Openstreetmap, mapquest, TomTom, bing_maps, plus caching.
Will changing back to this module and setting up caching reduce their mapping costs? What option within this plugin would be better for us?
Or is there a better option to using this plugin, can I utilise caching to reduce calls?
