I save more than $10/$50 by shopping at Aldi and SAM's club and Walmart for my groceries instead of Publix. I occasionally treat myself to a Pub Sub or Publix brand icecream (so good and still a 1/2 gallon) when it is BOGO but otherwise it's not a place for deals. The stores are nice but too expensive. I did buy 40¢ of garlic at Publix this week since I didn't want to walk further to Walmart to save 2¢. I looked around for deals on things I need/use but nothing else jumped out.
Publix stores are expanding in the Atlanta metro area. Definitely positioned as a premium-branded retailer with pricing reflective of that. The gasoline discount promo seems enticing at face value, but the $50 spend usually involves overpriced items at Publix, so the net gasoline price savings are greatly diluted in the big picture IMHO.
As an Instacart shopper for a fun, w*rk-at-will gig, I prefer these stores for customer orders since they are predictably organized, clean and have super helpful employees. A downside is that most stores have relatively small real estate (e.g. floor & shelf space, facings allocated to products is minimal). So product outages are more frequent with "sorry for inconvenience" tags sprinkled everywhere. Newer stores are slightly more expansive space-wise, but not a lot more.
That being said, as a retiree, I personally am NOT their target demographic. I have been on the frugal, price-sensitive spectrum all my life. It's what allowed FIRE to happen in my mid-50's on below-average earnings during peak years.
Publix BOGO deals might be the exception, but grocery store competitors in this area can result in significant cost savings for my personal shopping.
Kroger and sometimes Aldi are my personal go-to stores (each with their own +/-'s).
Fun to have options, but the analytic part of my pea brain always gets awakened with 'deals & promos'.
Happy shopping!
