Atleast here its not commercial before its at a scale that would be self sustainable as a business.
Below that is a hobby.
To be that size and do one off deals id say is rare.
I do hobby level reselling and ive found some sellers from the sections here but not really many deals.
I generaly dont do storage tho, as i dont keep stock of it to replace and its just too much risk with being responsible for 2years and refunding.
Those that do storage i can fully see snatching all.
The floor i use for lab/workshop would fetch about 1100$/mo rented out, reselling some servers a month covers that.
I know atleast 4 other active users on here reselling at same scale.
To me, the line between 'hobby business' and 'commercial' is a blur (and the IRS and Paypal thinks so too).
No one works for free, even for yourself. Getting 50-500x of something, inspecting the shipment, inventorying them (so you have 50-500 of whatever), then photographing and posting, writing up the listing, then the correspondence, shipping estimates, packaging, shipping, follow up communications, payments and accounting--you see this is some work. And no one is going to do all this without it being 'worth it' aka a profit. And for a 'hobbiest' is has to be even more than someone full time because a hobbiest is juggling a job that pays as well as 'life' that both take a cut if they're doing a 'hobby' of reselling like this. So at the end of the day, a 'hobby' is a full out, flat out business in the same manner, just not the same scale as full blown commercial enterprises.
It all depends. I know I could have made enough reselling the CDW memory deal I posted to rent a warehouse for a month and still profit. Just a deal a month would be enough to make it 'worthwhile' if I wanted to do that sort of thing (and part of me wants to, but I don't know if I want to have a parts warehouse business again and all the things that come with that). Depending on where you are and rents, it doesn't take much anymore. UPS delivers ground same day in a 250mi radius--that's pretty good for <3 days for a good part of the continental US.
It depends on what you're dealing in. If it's unobtainium imports that's a whole different niche than used M.2 ssds. The best source for storage is straight from the companies as part of a 'recycler' service. Then your cost of the hardware is free, there's some labor involved hauling it, but that's just a day job, and then the time scrubbing everything. TheMadDutchDude on reddit does storage pretty well, although you can tell from the prices that he's not getting direct from a company, but from recyclers who want to just move a pallet with a small markup without having to mess with it.
Thank you for confirming what the numbers would need to look like for an operation.

I was thinking it would be something like that, but wasn't completely sure.
So the big question is, have you bought a 'great deal' to use as either inventory for resale or as parts for resale? If so, why have you not just gotten a reseller's license to go direct to Ingram Micro, et al and buy cheaper?
