@Den-Fi Sales from Craigslist, Letgo, OfferUp, Kijiji, anything like that in the US are considered "garage sale items". From a legalese point of view, all that means is that once the item is in the hands of the other party, it's theirs. No right to refund, no right to exchange, zero ongoing consumer rights whatsoever unless those rights were stated and agreed to in writing. For instance, you can't say "six-month warranty" in an ad then refuse to provide service.

I don't stipulate as-is in my listings for two reasons. One, legally, that's the default. Two, stating "as-is" or "no refunds" sends up a huge red flag to a buyer that you're pushing junk off on them. Generally speaking, if the "disclaimer" section of your ad is anything more substantial than, "Cash only, price is firm. Must meet in a public place," or something along those lines, it's too long and you're chasing buyers away.

I also do not say anything about a return policy, period, under any circumstances. It's not in my ads. If someone asks me what my return policy is, my answer is, "I don't have one." My personal rule is that if someone comes back to me with a problem within a week or so of getting the PC, I'll help them troubleshoot it, and that's what I say face to face if asked. That's my out--not that I need one with nothing about returns mentioned anywhere and no commitment to accept a return given. That said, if it's clearly hardware, I'll swap in an equivalent or better part for them (looking at you, HD 6570 to RX 570).

I'll get this out of the way now: I list the exact specs in the ad, so there's none of that "AMD 8-core processor" that turns out to be an FX-8320E. I test everything thoroughly before listing it, including AIDA64, YouTube over ethernet and Wifi (if applicable) at 1080p or beyond, Heaven if there's a GPU even sort of designed for gaming installed, all of it gets tested over the course of a day. If someone wants Firestrike scores, framerates for Heaven and the settings used to get them, the peak temps in AIDA64, I've got all of that ready. If someone says their computer doesn't work and all they can give me beyond that is, "It's slow," I'm done right then and there. "It's slow," is code for, "I changed my mind," or, "I didn't read the ad and just realized this can't do what I want."

And both of the guys who wanted their money back? After being totally unable to articulate the problem to me in any specific way over the course of lengthy text message exchanges, the base reason came down to those two words. "It's slow." Am I spartan about it? Perhaps. But every time I've said something about returning the item, I've gotten someone wanting their money back because, "It's slow." If someone really pushes me on wanting some kind of guarantee or return policy, I just stop responding or, if I'm already at the meeting point, start putting the PC back in the car and wait for them to change their mind and buy it anyway.

It's so funny when people try to put the seller at fault because their reading skills never advanced past Kindergarten.

@Dan Castellaneta Dude, if you had any idea how many people would show up to buy the "Grandma's Trashcan Special" with a Core 2 Duo, HD 4350, 4GB of DDRs and a 160GB hard drive for $30 then call me back wanting a refund because it couldn't play fucking Fortnite after the ad very specifically said, "Not for Fortnite"...

I eventually just stopped selling those builds. Partly because I went from "buy anything" to "stop buying LGA 775 and AM2(+)," partly because I just got tired of angry parents on the phone because their kid still can't play Fortnite and won't shut up about it.

*facepalm*
