I think the idea of non-replenishing credits goes against the grain of typical lifetime deals so it can be a mental adjustment for most. I too had some hesitation after learning that this deal came with 100k in AI credits that will not replenish and I definitely considered getting a refund; but after testing it out, I think that it's worth it. It's actually a whole lot of credits and you only need the A.I. when there are items that you need support with- so it should last quite awhile.

I'd recommend to the creator to consider packaging the lifetime deal a bit differently - e.g., perhaps 5000k AI credits a month for tier 1, 10k credits a month tier 2 etc . When packaged in that way, most won't likely use up the monthly quota as they're less inclined to use it since they know they have it for a lifetime, you don't have to deal with the wide variation of costs since there's a cap and you can appropriately charge people for their usage over the lifetime. You also get more money upfront that you can invest into your business. I and many would pay a higher cost (e.g., $69) for a capped tier that we have for the lifetime of the product. If you're giving away 100k for $24, you definitely can give away smaller capped tiers that will add up to 100k or more over the course of several years. Wish you all the best!
