I remember getting some demo stuff from them years ago and wasn't impressed. But that was circa 2007, and a lot can change in 6 years.
With that said. You don't have to commit to using a single supplier. Some suppliers run out of things, so its good to have a back up. We have great strand pricing because that's our main focus, but we don't carry garland wreaths and a lot of the smalls needed. Some carry mostly garland and wreaths and have great pricing because of that....
You should have at least 3-4 suppliers ready to go that can support you.
