Durham Region's Safety Supplier | SupplyNow
I have used SupplyNow a lot in the last year and it is always the same experience. Prompt, great customer service and very quick delivery. I will continue to use SupplyNow for my construction business.
A very easy purchase and delivery process. Super convenient to order from an email and have all of my gear arrive the next morning via courier ready to be used.Steve G.
