For me, it would depend on what level of flip I'm doing, and what kind of supplies.
- Fixtures: mostly at HD, sometimes at Lowes since there seem to be more HD than Lowes around here.
- Tub, HWH (water heater), furnaces: plumbing supply house (San Jose, Oakland have plenty).
- Flooring: HD & Lowes if they have special (on sale items); Bedrosians, Daltile, Bullnose, Bay Stone, Porcelanosa, Terico, Uni-tile, KZ Kitchen, etc...
- Cabinets: higher end: custom shop; mid-low: KZ-Kitchen, Uni-Tile, semi-custom dealers (HD & Lowes sell them too).
- Paint: Mostly HD (good discount on my pro account); Kelly Moore
- Shower doors: less-known brands (imported) from stores like KZ Kitchen, some semi-custom models from Lowes; custom setup would be custom ordered.
- etc...
If you drive to San Jose (I think ~45 mins for you), there are plenty of suppliers around the Brokaw Rd area (off of 101 & 880). I would tour the area and get a feel of what they offer and pricing.
