Whenever these things come out, all it takes is a little Googling to figure out your reward amount without ever stepping into the store. Whenever a new batch goes out, there's always some forum somewhere out there with people talking about which barcode they had and what it was worth.
The barcode on the left half tells you the $ value. For this batch, the ones that end in 040598 are worth $10. (If you think your barcode ends in a 9, open your eyes a little wider and note the small 8 on the far right of the barcode.)
