I would not recommend that store for anything that you need, being tiles, laminate or hardwood floor, even setting material.
Although they have quite a good selection, everything is overpriced beyond reasonable.
They sold me some Laticrete epoxy grout for $150. Later on, I found it at Lowes for about $35. I usually use inexpensive sanded grout and didn't know about Laticrete products. The salesman got me into how great a product it is, especially it is stain resistant and requires no sealer, hence the high price. It is indeed a great product but it needs not be expensive for that.
Same thing with the mortar. I paid thrice the regular price.
I needed some extra tiles to finish the job and having learnt my lesson, I ordered from The Home Depot which in turn, ordered from the manufacturer. I was stunned at how much I had wasted buying from these guys. I paid the Floor Store $20 for some designer tiles sold by the piece. I ordered them from The Home Depot for $6 a piece.
And it goes on... In the end, with all the money I could have spared by not buying from the Floor Store, I could have had a contractor do the job in my stead.
The irony! I actually chose to do the tile job to save me some money.
