I missed this place many times at first driving down Franklin, but when I did stop by, wow!
The selection is naturally smaller than those of big box stores, but for DIYers and contractors, their prices are very competitive. I used their roofing and paper strip nails and decking screws, and they're pretty good quality, and got a couple of guns here as well (Hitachi, Paslode).
It's annoying when you've built up a good pace and cheap stuff cause jams or slowdowns, but their stuff is solid quality, and a lot cheaper to boot.
Location is not the best, but there is always parking available and I can load stuff up from the warehouse at the back.
