Vinted automatically nudges buyers to bundle when they favourite two or more items from the same shop — they get a small bundle discount, you get one combined shipping label, and the platform takes one set of fees instead of two. The mechanic only fires if there's something easy and small enough for them to add. A buyer who's already decided on a £20 jumper will add a £3 scrunchie or a £5 belt without thinking; they wouldn't add another £20 item, and they'd consciously decide against a £10 one.
Cheap accessories aren't really there to sell on their own — they're bundle anchors. Their job is to push a £18 basket to £24, a £25 basket to £35. I keep about 15% of my active listings priced under £5 for exactly this reason.
Sourcing: charity-shop accessory rails are dense with £1–£2 stock; the margin on each one is laughable, but the basket effect is real. VintSnap will generate the listing for a £3 scrunchie in the same 12 seconds it generates one for a £40 coat — so the time cost of adding bundle anchors to your shop is essentially zero.
