Also, supplies are often limited and rain checks aren't necessarily issued, so there are no guarantees.

Cyber Monday is the online equivalent of Black Friday and occurs on the first Monday after Thanksgiving.

Also, it's worth remembering that prices of merchandise sold in Alaska & Hawaii may be higher than in the mainland US because of higher shipping costs.
