How do i block a seller?

hi everyone, im just wandering if i can block a sellers items from showing when i search for stuff? i havent got paypal and have no interest in getting paypal and im getting sick of having to go into 20 items just to find one that accepts postal orders, basically what i want to do is block the sellers who only accept paypal, any ideas please? thank you.
