Best Materials is an eCommerce site specializing in selling supplies and tools to repair roofs in houses and RVs; they cater for regular roofs and also for hatches and skylights. Though the site is way too simple to be interesting –at least in terms of design—, it is also true that products are neatly organized into useful categories which you can browse at leisure until you find the products you came looking for.
I was shocked to see that the paint area gets no real-life reference for the colors: I reckon pointing to a Pantone is absolutely minimum information the site should present. But there are some good things to BestMaterials.com, namely the shipping estimator, which allows users to quickly check how much they’ll get charged for receiving the content of their shopping cart, and they can do this at any step of the way without providing any information that is not their ZIP code.
