Don't even have a Costco around here! Although they are building a Sam's Club about a mile away, but that won't be open for another 3 months!!!
Perhaps you can shop Costco online? (I have no idea).
Hey- how about this, i'll buy one for you at Costco and ship it to you. 15% handling fee ;)
I think you should make a day off it and find a place like sears or Best Buy. There must be a place within a few hours.
Since you will be spending at lease 2k. It will be worth the trip.
