If I order the max amount of flower for non Colorado resident on a Tuesday and I place another order online for the same amount on the next day could I pick up both orders on the 3rd day?

No, you'll have to go to another store

I dont think so it has to be 2 different days unless they are less then an oz each not sure how that really works

Just go to a different store after the first one

He's right

It's 1 oz per day, per store. So unfortunately you can't do that.
