They are not supposed to hold clearance items but IME it really depends on who you talk to. I was able to hold 2 Graco Nautilus car seats when they were on clearance a while back. Another time a store across town had a bunch of bubble blowers in the summer clearance that I was going to use as b-day party favors for DC and I wasn't going to drive all the way across town if they weren't going to hold them but the person said it was no problem.

People show themselves not by what they say but by what they do
Our happiness or our unhappiness depends far more on the way we meet the events of life than on the nature of those events themselves. -- Wilhelm von Humboldt
