I'll have a look, thanks. Your pricing looks much more reasonable - I suspect you're going to be seeing a large spike in demand.

Initial work on reducing load looks very promising though (lazy loading only when users scroll as far as the map on property pages, pooling map instances/dom elements and reusing them across a React app so that they're not recreated) - both things I really should have been doing already anyway. I guess that's part of the motivation for the change - even if I don't pay anything, I'm now costing Google less.
