Do you ever NOT buy something you DO need because it isn't a deal?
I saw someone ask if people buy something they don't need because it's such a good deal. I think everyone on this site that actually purchases items on this site are guilty of that (in the last week I bought 3 new video games, an 8GB flash drive, a wireless-N USB adapter for my desktop, and a external hard drive enclosure) Not a single item was really necessary but I will find a use for each.
However, items that I do need I routinely hold off on purchasing because I can't bear paying full price for them. How about you?
