I have never bought from their website, only from stores in person. They have a very wide variety of products. And the staff does not seem much for pressuring people into buying things, which is good. Their staff does not seem to be trained at all in pet care though. Sometimes you meet those who are knowledgeable, and some who are not. It seems to be all from personal experience though, nothing from training at the store. They do have good prices and sales though, provided you are a member of their "PetPerks" club I believe it is called. I find it to be a pretty good store to go into for certain products, provided you know what you need and why you need it, and aren't actually looking for any useful guidance on selecting a product.
