I totally empathize with you about the costs adding up. Hence the low price (note that plugin costs are prorated per usage). If you take a 6-month use into account that would be $24 (out of which bubble takes a 25% cut and tax folks take another 30% so as a developer I only earn like $1-2 per month).
I am really hoping the plugin store is upgraded with new pricing models atleast in 6-8 months. Whenever this occurs, I’ll dramatically reduce prices. In that scenario you’d actually end up paying less for a lot more. It’s a leap of faith on my end .
In contrast if things stay as is today (i.e. no new pricing models supported), you’d be paying the same as potential one-time pricing (of say $48) but only for the first year. Then at the same or lower price going forward . So it’s about taking that leap of faith on your end
