A note to the app developers - I'd make a bunch of impulse app purchases to deck out my upcoming shop…but I'm not paying subscriptions for most of this stuff. Most of it is not an actual service, just a one-time install!
Maybe it would make sense to have a subscription payment with a cap. After a certain amount is paid, you own the app outright.
I just paid a lot for two cool image apps from Magic Toolbox (magic zoom & magic 360), so I'm not saying sell yourself short. If something is worth it, I will pay.
But I will not rack up my Shopify bill to hundreds of dollars per month for the entire lifespan of the shop. That's just dumb.
