If you suspect them to be scamming

If you suspect them to be scamming, contact eBay with the user name and auction number. Also I suggest reading the whole auction cause some people will hide the fact that they add on a certain amount of $ (sometimes a pretty penny) and claim it to be a handling fee (though they should have it included in the S/H calculator, some will not and you’ll get hit with it when you go to pay). They’ll also hide other facts that they like to leave out of the main print/auction (ex.: Taxes for certain/all states, you won’t receive everything pictured or item received may be of different brand/look, Claim to have a warranty but then in their "template" say that it only applies to new items/still sealed when returned).
