You know I shop at Uncle bills on the south side rarely for several reasons. 1. 60% of what I buy there dies 2 weeks later, vs like 1% of stuff I've gotten at premium aquatics.
2. They are really the type of store to sell everything to a fool, hence adding to the dead fish population. Example telling a family who just bought a new tank, live rock and sand that it's fine to buy some fish to put in there...
3. They support puppy mills, since I'm not in approval of them I don't feel that buying other things there is a good idea.
When it comes to LFS I try to get things from those stores that really care about the hobby. Uncle bills in my opinion is the worst type giving bad advice having bad product, and adding to the uneducated reefers of the world.
