There’s a fediverse project called Flohmarkt, german for flea market.
fedi.markets is a european instance.
And here’s an article about it on wedistribute.org.
In the Netherlands we have Marktplaats.nl and Vinted is pretty big here as well.
In Sweden, there are e.g. Tradera and Blocket.
Facebook marketplace is also fairly active. I go there when for a chance to buy something for way less than it’s worth.
People on huuto.net know what a used playstation is worth.
People on facebook, don’t.
I know LeBonCoin in France and Wallapop in Spain/Portugal, curious to see what are the others
There is backmarket for thoses afraid of meeting fellow humans in order to do a transaction.
There is also a big markup on the price.
Both LeBonCoin and Wallapop have shipping integrated into the platform. Of course some sellers turn it off which is annoying but you can do most things without meeting a human.
You still have to talk to the seller, backmarket is the seller, you shop and click and it’s delivered, 0 risk of getting scammed (outside of the platform scamming you)
Yes, I never used Backmarket due to that. For “corporate” second hand, there is CashConverters and WeBuy
Bazoš, sbazar, aukro these are the main ones but there are also specific ones like cyklobazar.
Lot of stuff is also going through FB marketplace, sadly.
PS: I have insider info that there will be reworked version of sbazar coming this year.
In France it’s Le Bon Coin, or Vinted for clothes mostly.
Denmark has dba, den blå avis (used to be a news paper of sorts where you could trade). Owned by ebay. We also have a bunch of other services like Reshopper for everything baby related and gul og gratis which paradoxically is neither gul (yellow) nor gratis.
There is second hand shops and facebook marketplace is pretty common. In warmer season, we have “brocante” and “vide-grenier” something like a mix btw a garage sale and a local market. I usually put the things I want to give in a box and call my friend to check on it. For close I send a bag to a friend or neighbour, I know they will pick what they want and give the bag to someone else.
In Italy I guess the big one is Subito.it
We have Marktplaats which was bought by EBay in 2004. I personally like Tweakers Vraag & Aanbod for electronics.
