Kessel run and redeem codes question

You get progress not only for activities that you do, but also for cash you spend. 

If you look in the store, you can see that everything that has a cash price also has a coaxium value. This means that If you spend money, you get coaxium, which moves you forward on the Kessel Run rewards. 

For a while they were giving % discounts on buying from their store vs the Apple Store or other ways of purchasing. This was their initial way of encouraging engagement with the on-line store. Then they got rid of discounts (I think? Someone check me on that) and replaced those with the Kessel Run rewards. 

So you're not supposed to finish it. Only significant spenders are supposed to finish it. We get a minor "thank you" for engaging, but the bigger rewards are for giving CG your $$.
