I just steal my bags off of the elderly, the disabled, or the really stupid. Sometimes I sneak them directly out of saks after removing the security tag.
Ok, not really!!! I'm in a totally wierd mood today, lol! I put them on credit cards to get frequent flyer miles, then usually pay it off in full to avoid any fees. I've been slipping up a bit on this lately though -- leaving a small balence -- so need to be more careful. Maybe actually resort to stealing bags to save, LOL!
