A week ago sierra trading post in Eagan had some, Walmart has the Coleman brand at most stores I think you can check inventory ahead of time at WAlmart, Cabelas in owatonna had some 2 weeks ago…
I’d call ahead or do an order online for in store pick up to guarantee items if you are worried.

Thanks for the info! I’m not worried yet. In store pickup is a good call, I wish these could be shipped.
If/when I do find some I will be sure to let everyone know where to get them!

The Coleman is an Iso-butane/propane mix. I'm not sure if that's the same as what REI sells. I just haven't tracked down the chemical composition of the latter. It really confused my local hardware store when I asked them for that "iso" camping gas! :)

Found it (on the REI website):
"80/20 blend of isobutane and propane is clean burning, delivering superior performance throughout the life of the canister and in colder temperatures"

Most all Lindal valved canister fuels share the same base fuels, butane in some form and propane. The % mix varies from 80/20 to 60/40 Butane/propane with brand and use, more propane better cold performance.

You can buy them on amazon, granted they upcharge you to ship them. I've had no problems getting them off amazon when in a pinch when my local supply is dry.

The fuel for canister stoves is usually a mixture of either butane and propane, or isobutane and propane. Most brands use a mix of isobutane and propane (note the isobutane may not be completely pure and have a little butane in it). Coleman uses a mixture of butane and propane. So, the Coleman fuel is a bit different than the others. That said the butane in it burns fine in warmer weather. The difference comes when it gets cold out (below freezing kind of cold). To understand this it is useful to know the boiling points of these compounds. At one atmosphere pressure the boiling points are:
Butane 31 F
Isobutane 11 F
Propane -44 F
In order for a canister stove to work correctly you want to feed a gas not a liquid to the burner. The temperature that your fuel starts to liquify is a bit complex and depends on the mixture and pressure in the canister. However, the bottom line is that fuels containing butane will liquify before fuels containing isobutane. Hence, you will get better low temperature performance with isobutane/propane fuels than with the butane/propane fuel. If you are going in summer this isn’t likely to be a problem. In early spring or late fall, be careful. Propane, of course, would have the best performance at really low temperatures. However, getting much in a canister requires higher pressures. Hence, the propane only canisters have those heavy thick walls.
