These are standard prices on this side of the Great Lakes. The only ones with lower prices are the ones who locked in a multiple year contract, such as Wazee Sports, very near the deep site for training.

Maybe consider making the trip on our side then for cost savings if you plan on a dozen or heliox/ trimix fills for this dive season. The worst I've seen it up here price wise was $3.00 per cft in 2019 and when it was that high nobody had any.

Depending on how class scheduling works, I may very well do that. Instructor’s schedule is jam packed what with her full time job and other stuff, so next class day isn’t until sometime in July. I can deal with that. Gives me some time to practice stuff.

It is $5 in Ann Arbor.
 
I just swapped a K of O2 at my regular gas supplier. Price was up 25%.
Was getting it swapped for $40, now $50.
I have not cracked into the T of Helium I got for $75 last year. I know it is going to suck when I empty it.
 
A refill of 99.999 through a place my company has a contract through, and that we buy lower grades of HE from, $1750...
Thats not lab grade, just normal uhp 99.999 stuff

Assuming that’s CAD or USD Your company rate is beyond terrible and a huge markup over walk in pricing.
 
Yes and no. At nominal blends and pressures, the head temps actually run cooler.
Running 21/35 at 3500 psi, my heads will tend to be 10-20 degrees cooler than with 32%.
10/70 runs about 20 degrees warmer.
10/70 at 4500 causes lots of temp related issues. Valve life is drastically shortened.
As a comparison. This was running some 16/50 tonight.
I am running 23 degrees higher head temperature than with 32%.

I know, I changed the colors, sue me.
