Actinic bulbs, ooh. You can get them at any LFS here in Calgary but none really at a price remotely competitive to mail-order. But if you want to look around, try Big Al's, Pisces, Wai's, Riverfront, Ocean's, Tails-n-Scales. There are a few others but I can't think of them offhand.
Having seen first-hand for myself the selection of LFS up in your neck of the woods, I think I have to say this is one area we've got you beat (at least you guys got spared the snow this week though).
If you are going to only visit one LFS, go to Wai's.
Wai's Aquarium. It is on 16th Ave NE near Center St., across the street from Peters Drive In. This place is an absolute candy store! Compared to any of the places I found in Edmonton ... no comparison, really (although it's no Tropicorium, let me tell you. If you're ever in Detroit ... this is the LFS that all other LFS's could only dream of being. But I digress.) I have to say, Danny (Wai) has really chopped his prices compared to years past. I used to complain that his prices were too high. But nowadays he's actually pretty competitive. Whether this is because other places have caught up to him, or he's lowered his prices, or a bit of both, I can't really say. But definitely comparable to other places (certainly has the best selection of livestock in Calgary, and the healthiest), some things even better.
But, Tails-n-Scales isn't bad either (they're a basement op though so you have to call first to see if they're there): (403)254-9227 (I think... somebody correct me please if I'm wrong). Down in the DeepSouthOfTheCity(tm).
Or Big Al's (by Heritage and MacLeod), Pisces (up near the airport, McNightMare, er .. McKnight Blvd), Riverfront (downtown), um ... who am I forgetting ... there are a bunch of others that are worth a look, there's one just north of Wai's up on Center St. called Oceans I think, there's another one on 17th Av SE, but I forget the name ...
Enough rambling for now ... hope this helps. Post if you want any more info on any of them!
cheers
