I'd say the most expensive case I bought was the Apple Smart Battery Case for the XS Max a few years ago ($129).
The cheapest case was a Dynex Ultrathin Case from Best Buy for the XS Max a few years ago ($9.99)
Pitaka Air ($60 but got BF so 20% off + 10% off) was the most expensive for my 12 Pro Max. Generic clear cases from Amazon which were almost identical to the Totallee clear, soft TPU cases but $6.99 rather than $39 for the Totallee.
Most expensive - Apple leather case $60
Least expensive - $4 (Walmart and some non branded cheap cases) basically just to have some sort of protection till the other cases arrive.
Most expensive is loopy cases at $40. Cheapest is a case from Shein for $1.50. The Shein case is actually not too bad. I kinda want to try Casetify but always stop myself. And yes I have a phone case problem.
The most expensive case I owned was probably the mophie battery case for my iPhone 4 which was probably around $60 at the time. The otterbox cases were also one of my expensive cases, including LifeProof cases which were normally around $45-50.
The cheapest case I bought was also for my iPhone 4 and it was Speck's 'Batwell Candy shell' in the cotton dandy blue color for $24 on Amazon. I was obsessed with the color back in high school. Those were the days. haha.
