The have some great stuff that is worth every penny, and some crap stuff that is overpriced for soccer moms.
The running shorts are great - the band is not your standard nike-elastic, so chafing is non-existant on 20milers. The moisture-wicking and "butt vents" in the speed shorts are great for hot summer runs (I live in Atlanta). THey also have some silly but handy features -built in pockets for gu, keys, etc, that are great for training runs when you're hitting the streets on your own.
In terms of cost per run - I've also found the liners to last a lot longer than my asics/nike ones. Those shorts usually last a year or so, I have some lulus from 2009 I can still wear comfy (I should confess, I wash my running stuff and dry on heat, so sure everything would last longer if I hand washed/air dried, but I have other ways to spend my time!)
All this said, I love their shorts! I see no added value in their sports bras/shirts/yoga pants. Will grudgingly admit I bought a pair of their running pants since I loved the shorts - the pants suck. Hate 'em. Have ones I like better from Champion.
Thats my .02
