A buyer has asked me to sell an item separately from a bundle. I changed the listing to accept offers so they could buy and was willing to send the lot to them for the price they offered, because I'm nice. They then announce they have no money to buy item but keeps inundating me with messages that they have no money. They have not asked me to keep what's on the listing for them. It's a buy it now and anyone is free to come along and buy. Should I block them? It's getting too much
