From where I'm at, most retailers/wholesalers' businesses are booming, and it's kind of weird because it does not align with where we currently stand globally in terms of economic situation. Perhaps it has more to do with the current season (Christmas and New Year) with which a lot of people have
a lot of disposable funds and are not hesitant to spend it on basic necessities among other stuff. But come January after all festivities are over, I'm sure I'll see people being frugal as ever with what little remains of their money from the previous year. Retailers would surely have more of the market's share compared to wholesalers as people will have very little money left, and they will opt to buy items individually and would not have the chance to buy things in bulk. Due to the current pricing of everything, people are forced to do the more expensive route (without realizing it) by not buying things in bulk.
Also, online grocery shopping here isn't as popular as walking to your local grocery store/market and getting what you really need. I'd go as far as saying that we haven't caught up with the West's culture in relying almost everything online, and I think one thing that will not change any time soon is buying necessities - we will always want to buy it personally to assess the quality of the product and to see whether it's what we really need/want or not.
Buyers generally look for places that offer lower prices. Grocery stores and those selling other needs around the housing complex are at the point of imperfect competition or a form where there are only a few sellers, but many buyers. Sellers can determine the price of goods for any reason resulting in monopoly which can lead to injustice between sellers and buyers.
And in such a situation, your trade department/industry/organization should step in and freeze prices into what everyone deem to be a fair and reasonable amount. Price gouging has happened a lot of times here in the Philippines and the trade industry has stepped in countless of times when things went uncontrollably hard for the buyers to seek for items that are reasonably priced. Sometimes, it's not always the government that's the problem - for the most part it's the sellers banding together, hoarding these items and creating this imaginary demand in order to hike prices and take profits.
When market efficiency does not materialize and people are in a position of economic uncertainty, they will choose to find a place that can offer lower prices than the shops around them.
Which is true, but most of the time what they consider "lower prices" are not buying things in bulk and not doing the math before making the purchase. Economic uncertainties often push the public to make uninformed and unintelligent decisions that hurts them more than it can benefit them short-term.
