So I was trying to calculate all our CC rewards.

Discover $61.34 cash
Costco LAL $326.46
Costco DH $74.49
Chase Sapphire $300 Travel Cash Back
Chase Rewards $2115
Alaska $2550 (35000 * 5 + 30000 miles redeemed at a valuation of 1 cent per mile which is low. These were all redeemed at a higher cost. Plus the $500 on companion fare for card for hawaii ticket).

$5427 in rewards. It's actually higher because discover I use to get gift cards for restaurants and I regift them to people like teachers for starbucks. Hey $45 for $50 is a 5% extra cash back. I also get 2% on costco for executive membership that pays for $120 membership and then a bit more.

I normally do not redeem so much in flight miles and currently have used pretty much all our miles. We also have a bunch of bonvoy points from opening card which I need to use.

I think a more typical year is $3k in rewards. Not bad just for using a CC. Free money.
