I prefer to support local businesses whenever I can, and I generally accept that I'll have to pay a little bit more to do so. Happily, that's not the case with Grover's Pay and Pack. Grovers offers a very full selection of contractor-grade plumbing, sprinkler, and electrical supplies, and their prices typically beat Lowe's and Home Depot. The service here is unparalleled. I brought in a faucet once to ask whether I needed to replace a seal or the whole unit, and they ended up fixing it on the counter for me. I won't buy plumbing supplies anywhere else.
