I don't recommend using Poshmark. To me, it's more like a social media app than a secondhand marketplace app. You get random people following you and sharing your items that you'd listed out of nowhere. I don't like how they don't have an option where you can message the seller/buyer directly like Mercari provides. The notifications are so annoying about their poshparty stuff. Plus, their fees & shipping costs are so outrageous.
