Selling multiple items to one buyer on Vinted

[MickeyMouseEars]

I'm very new (as a seller) to Vinted and have just listed some of DS's clothes. Someone has made an offer for pretty much all of it which I'm happy to accept but all the items were listed individually as a 'small' item for postage. Obviously it's now going to be quite large (around 15 tops and jumpers). How does the postage work if I accept? Will I be in trouble for not sticking to the advertised parcel size?

It should adjust the postage to a large parcel. If the weight is more than large parcel weight, you could ask them to buy as two bundles but it ought to be ok.
You can turn off discounts for bundles in settings, for the future.

Vinted will automatically change the parcel size to be bigger
