Brian, I think this is the second query we've gotten here on the BBS with essentially this same text? Perhaps a re-wording of the text on the page along the lines of:

"As kits become available, I will reply to each email request on a first-come-first-served basis. You will only receive an e-mail reply with ordering details when I am ready to fill your particular order. These button sets are cast one at a time, by hand, so there will be a delay between the time you email me and the time you get a reply."
