Outside of free shipping I don't think they've put anything else out. It seems that since DFS website switched over to PetCo they haven't been running sale, and their prices seem a little higher too.
It seems to me that both LA and DD prices have gone up in the past month or two. Factoring in free shipping the prices once seemed to be 20 to 25% less than my nearest LFSes. Now they are close to par with them. With the price increases, I'll be buying at the LFS --- at least there I get to see what I'm buying actually swimming around.
