[White Dog BBQ]

I have a few bottles of commercial sauce, and I'd like to send some samples to my teammate that lives several hours away, which means it will have to go through the mail. These bottles of sauce are already opened, and say "refrigerate after opening" on the bottle. Ketchup also says that, though, and I see plenty of restaurants leave both BBQ sauce and ketchup out. Question -- can I send my friend small samples of sauce from an open bottle, not refrigerated, and will it spoil in transit? I just want him to try some; I'd hate for him to buy several bottles of sauce just to sample. Thanks.
