When 30 seconds of your time exceeds $7 in value, implying you make $7 million per year, buy a washer.

Now, if you want to be galled by the price, perhaps comparing it to the US Mint would help? I reckon the parent service is charging just about a third to half of what the mint charges for collector's grade coins [1] (depending on shipping). I think that's a fairly unflattering comparison. Even though I have some anxiety about asking a store clerk for something out of the ordinary, an extra roll of quarters for every four rolls is probably worth it.

What else can you say except that there's a sucker born every minute?
