Walgreen's started selling booster packs, so I wouldn't be surprised if Best Buy hopped on board the bandwagon. I've never seen Best Buy sell Pokémon cards either, but why not? They sell well, barely take up any room, and carry a high profit margin.
As for the illustration, Kagemaru Himeno is one of my favorite 2-D artists in the TCG. She's been around since the Jungle sets, and I love her soft shading. She always draws in such a way that you can look at the picture and figure out a small story she's made with that Pokémon. Unfortunately, it's a bit hard to tell with this one, as the holofoil makes the background impossible to make out.
