it's my understanding that anyone who wants to fudge the amount should realize that by doing so they are almost certainly committing fraud, they are violating several US and whatever the foreign country is laws and regulations, and they are risking a fine and/or jail time for doing so.
Needless to say I don't fudge. The SELLER is the one who will get into trouble if anyone does, not the buyer who asked you to do it. Just keep that in mind. Not worth breaking the law in any way.
