I've been with them for over a year now, a very good designer friend is also one of their spokespeople.
Clean, big show room. Knowledgeable and helpful salespeople that take good care of you. Overall.
In Toronto, they no longer do the 24/7 access.
They are not the cheapest. What others say above is correct, they mark it up then give you a discount. I believe it's 50% on carpets, and 30% on tiles/hardwood. I think that's most items, if not all.
The upshot is, you have the option to either give your client the full discount, a partial discount, or no discount.
You call in, set up a time and let them know your client will be dropping by or you go with them. They walk you through the selection, answer questions, and the clients can see the sticker price on the material.
I have never personally made any profit off my clients. Not yet anyways. I like the idea that the client is taken care of, whether I'm there or not. Then, when they learn that I'm extending my full discount to them, they are very pleased.
With the full discount, their prices are competitive. And for the uninformed client, it wins me a good amount of credibility to boot. Meaning, they could have probably got the same material somewhere else for the same price, but they feel they got a discount and that always makes people happy.
They only sell the material, and I've found that they want nothing to do with you after they have sold it. If you call with some questions and they don't see money in it their attitude changes pretty quick. That's the difference I've found with them vs other companies that will take the time to help you out over the phone as a loyal customer. I.E., I called them after one hardwood install to see if they know where I could buy some wax sticks to match the flooring I bought from them and never got a call back after 3 messages. Mind you, I didn't purchase 20000 sq/ft of material, but I still bring them business on the reg.
All in all, I like them, it's a one time $20/$25 annual fee. You can sign out material to show your client all you want. Overall, I like them. The biggest upshot is the credibility with clients when they get the full discount.
