What is your goal? To build a business so you can quit your job? Or just make a little side money? That will really inform your strategy more than anything. How much do you need to make? If you are funemployed now, building a flipping business is not something you can launch right away unless you have significant capital and know where you will source your products (or you have a very low cost of living)

Personally I would recommend ramping up slowly as a side hustle while using another main gig to pay your bills.

Markets and trends fluctuate a lot and sometimes stuff that was selling a lot just stops or other sellers start listing the same items because they are following trends. There are pros/cons to every marketplace (facebook, ebay, poshmark, etc). There are different strategies for each of those, different pricing models and inventory models (how many units you need to have on hand, etc).

I know eBay has "eBay envelope" for like certain collectibles but that's limited by category (that service also has never worked for me), so perhaps this seller just has a custom shipping rule that is that low? But they would lose money on a sale like this. I suppose the hope could be that people buy multiple items at once if they have plenty of (in this case) retro games

I've noticed there are a lot of like lifestyle blogger reviews and what not but most of them just accept the word of the companies that advertise zero waste, plastic free or ethical sources of natural materials.

I was checking out the Zero Waste Dish brush kit and it looks reasonable but I can't find any certification bodies or orgs

Usually strip malls but these are stealthy dumpsters because Doordash doesn't usually advertise their Dashmart locations very visibly - but they toss a ton of stuff (ugly produce/bread, anything past its best by date)

You can check on the doordash app I think for the address of nearby dashmarts

I've heard for years these companies are horrible (musk ran paypal for a while right?) Are there any easy to use alternatives? Well besides CashApp, I've heard they aren't great either. Just a reminder to anyone using venmo to change your default privacy settings from public to me only.
