Going Christmas shopping with my wife last December brought us both to Walmart. Walking past the usually barren card section, must to my surprise were 4 hangers of 2020 Heritage Update. (Since then, the card section has been replaced with something else leading me to believe that they are no longer going to carry cards...we will see. Thanks flippers!)
Only eight cards here. Looks like I scanned the last card of this pack in with the first pack of the first box. Oops.
Ok, so it appears you don't get a hit in every box. I do like this set...although there were way too many duplicates. I just wish it wasn't so darn expensive.
