For me the question is availability, there is really only one good size card shop still in the area so retail and the flea market have been the best local options. The local Target and a sporting goods store chain (short for Richard's) had some individual rack packs as well and would seem to make the odds more fair. I try to stay away from the loose retail packs as much as possible, but enjoy opening a blaster box now and then. My luck has not been good with pack or box pulls from anywhere recently, but I have not seen a huge difference in the odds for me. I am sure others may feel differently...
