I most generally use my bag the same or next day. Sometimes, I even change out bags in the parking lot. I think that would constitute ASAP!!
That's me: in the parking lot AND THEN I GO BACK INTO THE MALL OR SHOPPING AREA TO CARRY THE BAG!!!! I always carry nail clippers to remove the tags to make the changeover complete!!! People may think I am window shopping but I am admiring my new bag in the reflection of every window!!! LOL!!!!
