Chase is still offering 5% on groceries. Here are the terms of the current offer:
5% Cash Back in the grocery store category (excluding Walmart and Target) until the earlier of the end of your first 12 months or first $12,000 spent: You’ll earn 5% Cash Back rewards total for each $1 spent on purchases in the grocery store category (excluding Walmart and Target) made within your first 12 months from account opening, or until you reach $12,000 in grocery store purchases, whichever occurs first (4% additional Cash Back rewards on top of the 1% Cash Back rewards earned on each purchase). The additional 4% Cash Back rewards will appear on your billing statement in a separate line from the base 1% Cash Back rewards.
If your first statement period ended 10.18.2020 your 12th statement cycle ended 9.18.2021, but if the first cycle was short it should run to 9.30.2021. This should be very easy to confirm with Chase customer service.
