what do you do with 'silly' offers

yesterday i got am offer on an item, less than hlaf the asking price.

after i declined the offer i recieved a detailed message explaining my prices are way too high, must have taken him a while to type it all up.

i replied with 'you know what you can do with your advice'

i then added him to my blocked buyer list.

i then got 2 messages including bad language.

i left it at that

now today i wake up to another silly offer from a different person

$40 including postage to the USA for an item i have listed for $250

i guess guy 1 has a mate.

none of my items has 'make an offer'

cheers for your input guys.
