Hello, I would like to know how to send a bulk offer for a single item that has multiple favorites, which allows the first person to accept quickly.
This also allows making an offer for one person at a time.
Thank you for your help.
Hello and welcome! 
So, I don’t know if I understood your question correctly, but if I understood correctly: you’re asking how to make a bundle offer when you have several favorites from the same seller, is that right? 
To answer you: Simply select one of the items you wish to purchase from this seller, scroll down below their listing, and click on the « create a bundle » tab. Then all of this person’s items will be offered to you in the same sale, and you will be able to see what you are saving thanks to bundle discounts (if the seller has activated the option). Once everything is selected, you will need to « view bundle » to proceed to payment.
I hope I understood your question correctly and was able to help you!
Hello!
I don’t know if you are asking as a buyer or a seller?
Mandinfintiy answered from the buyer’s side, I will answer from the seller’s side 
You cannot send a bulk offer.
You can either lower the price and in that case, everyone who has favorited will be informed, or send individual messages with an offer… or via Clemz in an automated way

Thank you for your response. This is indeed the case, there are 2 missing features on Vinted:
A bundle offer to all favorites on a single item
Searching for items in my closet, I have to go through all the listings to find an item to remove if it has been sold elsewhere.
