i would agree that most are but there are a few who have some decent deals/specials.
the BC Compassion Cluc has $6 specials that are worth it for sure but then you have a restriction on how much more you can buy. like if you chose to buy the $6 special, you can only buy $26 for you purchase. they do this so that the folks with a few extra bucks can't come in and buy it all. they have nothing over $9 for buds...but then if you need more than 5 a day that's still way up there.
i agree with you that most are the same but at least going to a CC or Disp, you can see and smell instead of relying on a picture.
