I ordered them, and no they didnt come that fast. It was about 2 weeks and I was sweating it a little that they had gotten lost. I'm not sure if they have an express delivery?
Thanks for the info, lindalinda. I decided to spend the extra $12 and express them (even though that is still up to 6 business days) and not be frantic the day before we are supposed to leave, worrying about them.
Called my local Costco and they said that they have them in-store, so all I have to do is stop by to purchase them. If you have one in your neighborhood and are concerned about the mailing time, I suggest that you call to see if they have them at the store.
