As near as I can tell, the problem with Online Bills for Shop Your Way MasterCard by Citi is that there are data entry errors. These errors can only be corrected by Quicken Inc., not us users.
When Quicken Inc. changed the way we connect with Citi Retail Services, the Online Billing URL entered under Shop Your Way is incorrect. It shows "https://www.shopyourway.com/today". This URL is for accessing the Shop Your Way Rewards system, not the Shop Your Way MasterCard Account. Attempting to use this entry always fails.
The correct URL for the Shop Your Way MasterCard Account is "https://citiretailservices.citibankonline.com/RSnextgen/svc/launch/index.action?siteId=PLCN_SYW#signon". When connecting for downloading transactions, entering the above citiretailservices URL causes Shop Your Way to appear as a financial institution, and I connected that to the account register just fine. When entering the citiretailservices URL in the online billing search, 10 entities show up, but none of them are Shop Your Way. All but 1 of them have the same base URL with different values for ?siteid= . Since none of those values is PLCN_SYW, none of those entries will get me my bills.
