As it is a really big help for extending your territory and allowing you to get access to tons of resources, thus being locked behind quite some investment. Gives a little challenge to make it valuable.
If you can´t wait for it or can´t afford it:
1. Go to your mod folder
2. Extract artillery-bombardment-remote-reloaded_1.2.0.zip to a folder with the same name ("artillery-bombardment-remote-reloaded_1.2.0")
3. Delete the zip
4. Go to the folder artillery-bombardment-remote-reloaded_1.2.0 and open data.lua in an editor
5. Change line 145 and 163 to change the technology costs
- smart_technology.unit.count = 25000 (25000 is the amount of flasks / technology cards each that are necessary for researching the technology, e.g. reduce it to 2500 to only need 1/10th of the flasks)
Consider what is easier, farm the ressources or make the modification to the file. Both will bring you the technology you need :)
