Kind of related, ( not an idog, but still kinda sneaky) about 2 years ago i was at walmart for BF and they had new release dvds for $8 that went off sale at 11. I was in line at 10:49 and they tried to tell me that was full price because they scanned me at 11:01. My point is, if this happens ask to talk to a manger because I did and they told me (at least at my store, if you are in line before the cutoff, you are ok)
