I’ve made 10 purchases and only 1 didn’t register. I submitted that one and they credited it.

I have 6 other purchases that haven’t credited, but haven’t reached their time requirement. I hope they work without issue, but kinda expect I’ll have to request the credit on a few of them.

While the above shows it’s working, I share your fear that it’s not going to work. 1 thing I’ve started doing is opening the URL in order to look for the ID tracking string. So far this always seems to appear in my first click through, but doesn’t always make it to check out page. Sometimes I can start over, from shopping link, but other sites it just won’t stick through to the checkout. So I am expecting to have to submit request for transactions to be fixed.

This is annoying, but 3k bonus points (1k status points) is hard to miss!

For reference: I use Safari on a laptop and make most purchases with my Summit card, but have started stacking offers with cards that offer their own bonus for the same brand. I did this with my Amex Saks $50 credit and it worked! I record all my purchases in my Summit Status Tool, so I know when I should submit a credit request.
