While putting some cards away I discovered that the two different width magnetic strips on the 8th issue Sam's Town Tunica Prime Rewards and Prime Rewards Golden Gang are in fact two different issues of the same card. On the cards with 11mm wide mag stripes the Gambling Problem text above the mag stripe is approximately 13mm above the first line of text in the paragraph below the mag stripe. On the carsd with 12.5mm wide mag stripe the Gambling Problem text is approximately 15mm above the first line of text in the paragraph below. So I've got them now listed as 8a (11mm mag stripe) and 8b (12.5mm mag stripe) issues. Changes should appear on the ChipGuide tomorrow.
Here's the cards I'm talking about...
