Always get these messages. I had a seat from a van for sale on ebay starting price 0.99p. No end of messages asking do I have a buy it now price.
I respond with its an auciton I’m leaving it run unless you cna make me a sensible offer. 99% never replied. One replied with
“I’ll offer £10 no one would pay for more than that….”
I left the auction run and sold it to a guy for £200 who drove 3 hours to get it.
moral of the story. Ignore them and leave the auction run.
