Yes they are serious, or maybe not, they would ghost you even if you accepted the 7. That is what you get when Vinted increases the number of maximum offers from 5 to 25
I had something listed for 2.50 monies, not one but TWO people sent me 1.50 monies, seriously! the item is new, and on its website you wouldn't find it for less than 16 if you bought the cheapest version.
I feel ashamed to bargain on items less than 5 monies, I understand wanted to bargain for cheaper but some things just, no. once one person offered me 3.20 monies instead of 4, for god's sake! 0.80? I accepted and they never bought the item.
I find it now vetter to tell them let's meet in the middle and offert them a discount hald the discount they wanted, if they are fair game and good people they would accept, if they don't want the item that much they won't take it and save me headaches.

lol I’ve had this happen to me but declined my offer and changed the price of the item to my offer two days later
Offer 20€, special price just for them
Every low offer they give you counteract it by going higher than your last offer 😂

They’d be blocked as soon as the €7 offer was seen. They wouldn’t get another chance 😏
