YMMV but the sale price for oats at our Sprouts is 0.69/lb, higher than Costco.
I've bought rolled oats, quick oats, and steel cut oats at $0.50/lb at Sprouts when it is on sale. I've bought 50 lbs of it at a time. Sometimes they are out in the bins but have bags of it in the back. I've bee quite successful with this at Sprouts. Plus if it is out get a rain check and come back the next week when they resupply. Last time I checked Costco wasn't better than that. What is it these days? Online it says $10 for 10lbs. That can't be right.
Cheese is $2.99/lb on sale at Sprouts, sometimes just $3.99/lb.
2. Don't shop for price only, are looking for quality (aka, actual olive oil not a blend of oils). Or are looking for business practices, like paying the employees a living wage. (*cough* Wally World)
This is not the point. Can you live on a blend of oils? Is that not okay just like choosing to buy generic at the grocery store? We survive just fine on those things. And if you want to make a charitable donation to Costco to support their practices by paying more then that is again a luxury. I could just as easily support other causes.
3. Don't shop for price only, are looking for a certain amount of convenience.
Again - convenience is a common excuse. If Costco is 0.5 mile from your home and you can bike there then fine. If you pass three other perfectly good grocery stores on the way, then mmm, sure?
Let's not pretend that we know everything, mmm kay?
The whole point of this forum is to bring up points of our own knowledge. My response to Costco is what I know. If you just want people on here to agree with your way of thinking then just don't respond to people who challenge your own knowledge. Or are you saying you know everything?
Costco: 0.55/lb for oats. Sprouts: 0.69/ lb is the sale price
Costco: $1.99 - $2.49/lb for cheese. Sprouts: $3/lb lowest price I've ever seen, and that's the same for any other grocery store. (This is sharp cheddar, by the way).
Olive oil: I've done too much research I guess. I want actual olive oil, not a blend of oils. If I wanted a random blend of oils, I'd buy them, and not expect to be paying a premium for actual olive oil.
As far as "knowing everything: - I'm specifically responding to people who talk about Costco being "ridiculously luxurious" and "obviously you are paying a premium compared to the grocery store" when...no. I created my price book back in 2001. I kept it faithfully updated for 10 years. Like, on the computer. Now I have it all in my head. And I know, for sure, that Costco prices are cheaper on a large # of items that we buy regularly. I know this because I check regularly. I still look at the flyers. Any time I'm in a store, I wander past the sections of interest and check current prices for unadvertised sales. In the last 5 years we've gotten a host of new stores (including Sprouts, which I love) and I've checked them ALL out, even down to knowing that Sprouts has the best bulk price on oats (even though Costco is cheaper per lb, if I buy in the bulk bins I avoid generating new trash), but Smart and Final wins for dried beans and rice and lentils. Whole foods, for some reason, has cheaper corn meal and the best price on tahini.
It's no different than people saying "obviously it's better to shop at Aldi" (no Aldi here) or "obviously you should shop at Walmart" (no Walmart either). The point is that grocery prices are HEAVILY location dependent - they depend on the general cost of living in a particular area (overhead), the type of store, the specific location (cost of rent, cost of transportation to get the food there) and size of the store (pretty stores are going to be more expensive than the dingy 0.99 only store with no parking), competition (if you are the only store in miles, you can charge a premium). I'm always shocked at the cheap prices at the Walmart when visiting the inlaws in upstate NY, and equally surprised that the prices are so much higher when visiting family in rural PA - but as most of the other stores went out of business when Walmart came to town - I guess it's not too surprising.
It's completely ridiculous for anyone to make gross generalizations about the cost of groceries in any area where they don't currently live. Which is why you will OFTEN see suggestions to do a price comparison yourself, because it depends. You will also see suggestions on "different types of stores" to check out. A lot of people don't think beyond the typical grocery store. You have to think about the Mexican, Asian stores. The 99 cent stores. Scratch and dent. Day old bread. Big box. Food 4 less. Trader Joe's. Farm stands. Farmer's markets. Every area has their own "mix" of stores, etc, and you pretty much have to check them all out to find the best prices. AND you have to decide what you are shopping for besides price. Like I'm not willing to drive the 30-40 miles to Aldi, but I actually had a coworker years ago do that same drive to shop at Walmart, all so he could save money on canned vegetables and ramen.
By the way, the cheese and milk savings alone save me $130 a year. I guess I could save more if we gave up dairy.
