DIY car wash prices $4-5 for 3 min?!

I’ve been to a few DIY car wash spots over the past year and is it me or have prices on these joints gotten totally out of hand? Some are up to $4-5 for three min… can be up to $15 by time you’re done, which is wild for a DIY imo. Sadly all the $1-2 spots are too far from me (I’m by DVP & Eg). Crazy work.
