Just received my refund today, it was bigger than I expected. I did the math on what I thought it would be but it was almost double that.
I did the math on ours and it was pretty close to what I expected. They might have added a percent or two on top, or rounded somewhere, but it was pretty close to what it was supposed to be.
Got mine today as well. At first it seemed higher than expected ($200 and change for x2 Sig+ passes, monthly, charge day 27).
Then I remembered the down payment as well. Adding that in evens it out to about right.
