Walmart is notorious for giving things odd abbreviations or hard to see receipts. I do tell people to look over your points because sometimes you don’t get them like you should. I just leave them until the end because they are only 5 points.
It’s a bit worse lately because now you accept fast food and restaurant receipts. I have run across running out of submissions because I have more than 14. Sometimes I like the feel or smell of a brand better, sometimes I like the value of the the generic brand. I buy both brand name and store brand products.
