Breeze litterbox cost vs. regular litterbox?

Hey guys!
I was just wondering if anyone has an idea on the cost breakdown for maintaining a Tidy Cat Breeze litterbox compared to a regular one? I have a Breeze box and I was thinking of replacing another litterbox with a Breeze but I am curious if it might actually cost less in the long run?
I find myself having to change the litter in a regular box very often because I have multiple cats, and it gets very expensive...

It sounds like you'd be a good person to save your receipts or otherwise keep track and tell us which costs more! Do you know already exactly how much you spent monthly on clumping clay?

I've switched to the Breeze, and I think the cost is very similar, but I haven't kept track so I don't actually know.

Hi, I am a welcome breeze litter fan here for just over 2 months.
I think it costs me about the same as regular litter for myself
our maybe just a couple extra dollars per month.
It is not very significant $ for the change and I sure love
the lot less work and litter everywhere. Great value for me
For first few years I dumped clumped litter every week but this
past year due to higher costs I moved to twice a month just
adding a little extra at the end of week between.
Since the breeze, I put fresh pellets now every 2 weeks. I could probably due at 3 weeks just with one cat, but I dont.
