For years I've seen the same items cluttering up Etsy, Ebay and similar - wholesale items, for pennies each, bought in bulk. You see them being sold for higher prices on nicer websites with fancier photography, or mounted on prettier cardboard, but it's still a 29p necklace.
Anyway, I've been reselling vintage finds for a few months and it's done rather well so I'm thinking of putting in A Bit More Effort and adding related items to the shop.
But is this really worth it? One item, for example, was being sold on Ebay by 81 sellers and over a hundred on Etsy. It hardly seems worth attempting to compete - unless you rely on impulse purchases while they are on your site for The Main Item, or you under-price pack 400 orders a day just to break even.
Or I'm way off base and people don't mind that decor is fairly common across the internet, or don't realise because they don't search much.
