In the past I have taken "orders" from individuals and represented them at the Auction. In a nutshell, once we send out the list of items, contact me (or one of the National Officers), tell me what you would like to purchase or bid on. At the night of the auction, we will purchase your tix., and or bid on your behalf. In the past I have had people tell me, "...I would like to bid up to $XXX.XX on such-and-such product". I do the bidding on their behalf and let them know if they have won. I have also had people send me $$ and say "...buy me 10 tickets for the Purina raffle, or bucket raffle, or..."
So yes, by all means it can be done. I had pretty good luck last year for those I represented.
