Check the store.
Check on their website. You can compare with other stores who has the best deal. I doubt anyone here will know off tye top of their head what single item costs unless they buy it on a regular basis, plus theirs different prices on different sizes.
That seems like a silly question to ask publicly on here, why wouldn't you just call them? I am sure that there are different brands, types and sizes of this product and the staff there is very helpful with any questions i have ever come to them with.
