Send them a list of names (real names, not screen names) of people who wanted to buy each MP but couldn't due to lack of supply.

Emphasise for Optimus that its Especiallt disappointing as he was a catalogue item, and insufficient supply is even more disappointing (you could mention its also frowned upon to have little-to-no stock on advertised items, but we want to keep them onside).

Also mention this is just collectors of one board, not representative of the total collector base, and not even beginning to take parents into account.

If the list is big enough include the dollar figure at the end, ie they missed out on $XXXX of sales due to low/non-existent stock. Can't argue with the dollars.
