Slightly off topic, but I have a $500 card purchased at a supermarket that has now twice been rejected for MO at a supermarket. After the first time I checked online and confirmed I had the correct pin. It shows $500 value still, and no transactions except for initial load, although it did show today as last use. I have liquidated many identical cards without issue at the store both times when I had the issue (just replaced it with a different card). Expiration date is same as some that worked. Thoughts?
