The grocery industry is heavily monopolized. No where more so than on the west coast. They don't care about their reputation because there mostly is nowhere else for you to legitimately go to.
Nearby: Safeway, Lucky’s, Target, Trader Joe’s, Ranch 99, Costco, Walmart, Cardenas, Pak N’ Save, and I’m sure I missed some. Also, a lot of Asian food marts that aren’t chains. That seems like quite a lot of competition?
Safeway is owned by Albertsons. So is Lucky's. There are 58 total Ranch 99's in the USA. Costco requires membership up front. Cardenas is owned by KKR. Pak N Save is a subsidary of Safeway and also owned by Albertons. Walmart is not a grocery store.
So, no, not a lot of competition.
You really should look into grocery M&A's over the past few years. This is all easy to see if you care to _actually_ look.
Walmart is the biggest grocery retailer in the US with a solid multiple more sales than the next largest, Albertsons/Safeway group (per WSJ article in last month or so, don’t have link handy)
