I've always sent my parcels on Vinted via Royal Mail.
I used to take them to the Post Office but lately (for other parcels- not Vinted) I buy postage online and my postman collects them from my house. I get an email confirming collection.
I want to start selling again on Vinted but would like to have the parcels collected from my house.
I'm not up to date with the T&Cs and doubt this query will be covered on the site.
Is that email enough proof for Vinted? Is there any way I can upload it as proof of postage instead of a photo of a cert. of postage (the paper receipt from a post office)?
