Discount Builders is an excellent store, San Francisco's answer to Home Depot. Their regular prices are always reasonable, and sale items can be the best deal anywhere. It's the best I've found for big things like lumber, sinks, vanities, etc., and for large quantities of things like if you want a whole boxful of a particular kind of wood screw. They offer a quality selection of many items, including good quality, although sometimes the low end can seem to emphasize ""Discount"" rather than quality. The staff are always courteous and usually very knowledgeable, the lumber is great, and it's a pleasure to shop there.
Pros: excellent staff, wide selection, low prices
Cons: no website
