Wet side O-rings?

[twistedfinn967]

In need of a couple of wet side O-rings for my MP-40qd's. EcoTech sells them for $2.43 each. Great, right? The problem is that they also charge $15 shipping on said product. I emailed support and was told there is nothing they can do about it. I'm sitting here doing a slow burn over this. Interweb search comes up empty as far as anyone else selling these. Has anyone found them anywhere else or have a better idea?

TIA

Do you know the technical size call out for that O-ring? If you have a Grainger near you I'm sure they could match it up for you.

That may be worth a shot, thanks!
