Bait & Switch BS at Home Depot! (Caution! I'm still worked-up here...)
Looks like a regional price difference. I'm also noticing it's $419 if in-stock and $383 if shipped. My guess is that hazmat shipping charges might apply and they're getting tacked-on where it's in-stock but that's a random guess.
Either way, HD's system is FUBAR and a total pain to deal with. Except for lumber I mostly have stuff delivered because the in-store experience is a disaster. If it's not the aisles full of garbage, it's tools locked behind cages and no one has a key, or it's a whole goddamn family reunion with 27 dogs barking and pissing in as they block every aisle. Luckily we still have some local/regional places that cater less to the instra-gram inspired.
