No change.  I have 2 main suppliers I use, 1 kinda local, the other is a couple states away.  Get prices, go with the cheapest, place order.  Sometimes if it's a push I'll throw more 1 way or another.  Not much differnece in price, if I had to pick just 1 to do business with, my budget would be fine.  I always listen to input on what they have and are promoting but I'm responsible for knowing the chemicals and how to use them.  I don't just do this cuz someone said.
