As on Aug 30, Chase narrowed their dining categories. Not sure if it was linked to the rollout of the CSR, but the following MCCs are no longer part of “dining”. This is from my SM with Chase.
The following merchant types have removed from Restaurant categories.
– Dairy product stores
This affects both points earning as well as inclusion in Chase’s Blueprint payment plan. These MCC are no longer part of any special categories, so be prepared to see 1x earning on some of the stores where you were earning 2x / 5x earlier and were expecting to see 3x with the CSR.
