Also, keep in mind that if you are selling high dollar pins, many pins, or just a lot of items in general, paying for an eBay store can significantly reduce your fees (at least, if the items sell). A Basic store subscription is around 28 bucks if purchased month-to-month but you get double the free insertions, the eBay specific fees per item drop from 10% to 4.915%, and the max per item fee paid drops from $750 to $350.

Justify it however you want, but technically.... Yes. Use Facebook or CL or LetGo or the million other apps/sites available if you want to post items for sale and not pay the fees. eBay fees are the price you pay for getting your item in front of a large buying audience and not having to make a face-to-face sale. Inserting listings on eBay just to use them as a vehicle for your ad to sell outside of eBay not only takes legitimate sales away from eBay, but also promotes shitty buying and selling practices and turns other people off from using it. I hate when I see something I'm interested in, start watching it, and then it magically just disappears or the listing is ended. More often that not, this is why.

Might be good for you and the buyer in that particular circumstance, but fee avoidance just helps drive higher fees....then people bitch about the fees and try harder to avoid them.

Kind of like how everyone sneaks candy into a movie theater but then also complains how the theater charges $5.50 for a $1.50 pack of Sour Patch Kids....
