Just make sure that the cashiers check completely clears your bank before you ship the goggles. There are a lot of folks these days getting cashiers checks that are no good. They ship their goods and then the bank notifys them later on that the check did not clear. Best thing to do is tell him you want a U.S. Postal money order. Then go to the P.O. and cash the money order before you ship the goggles. That way you have cash in your hand.
