Negotiating a raise with a salary + uncapped commission job

Hi All,

I work as a sales consultant for a large company. I work full time and have a base salary + uncapped commissions. Prices everywhere are absurd because of inflation and the market certainly seems to indicate that asking for a raise is reasonable. When I float this idea around to some people at work the counter I get a lot is, “well we have uncapped commissions so…”

What are some good negotiating points to counter that argument? This would be a raise to my base salary only of course.

Thank you.
