advil nighttime/nighttime liquid gels/liquid gels/large size??

[pamjcoupon]

there are so many advil coupons right now. Does anyone know what can be stacked?
I have
advil nighttime liquigels (40s) upc12922635 (tear)
advil nighttime liquigels 40s upc 12923087 (tear)
advil nightime liquigels upc 12922794 (print)
there are also the advil any large size upc 12923045 (tear)
and I know there are a few more printables for advil large size

I know the first 3 can be stacked, but what about the advil any large size... it doesn't say nigthtime, but it does say liquigels?? and the other printable?? does anyone know. I am so confused by all the advil right now.

The any size Advil can't be stacked with the Nighttime; it states on the back which sizes are applicable and as far as I know, there aren't any Nighttime Advil bigger than 40's.
