These companies definitely make a profit even with the black friday prices. Here's a great example a few years ago at Best Buy......they had a Sony Pentium 4 2.6 Ghz computer with a 15 inch Sony LCD monitor(don't know if some of u remember?) for $1,200 after a $800 rebate. The catch was that while in line they would add stuff to your cart without asking. The BBY employees would immediately put what they called "packages" (bronze, silver, gold)....it was somewhere between $100 to $300 bucks. They tried to put the $100 accesory package (surge protector, air duster, mouspad, USB cable...etc) on everyone's computer right when you picked it up. I was like hell with that and put that junk package back on the shelf.....and it doesn't stop there. While in line they would have these check points where at first it seems like they would like to help you check out the line faster by making sure you got what you wanted. Instead they would try to stick you with those packages again. If you didn't want it then they would try to make you buy the more expensive packages or even single accessories since they knew you know that stuff in the packages was cheap (probably less than $15 bucks worth of stuff). They tried to sell me Monster cables (which by the way has like a 300% to 500% markup) and USB gold cables. They wouldn't leave until you said yes to at least one item.....so I did but when they left I just threw it on the shelf. I'm like wtf....it's like WWII with all of these check points. At the end they even try to throw in the 2 year service plan and rang me up for it even though i said i didn't want it. Finally I said NO and they relented. Case in point....they still make up to $300 bucks or more when they sell those computers and some of those computers like mine was custom made so BBY of course had to get a discount in bulk. Heck some of the customers fell for it. Some who bought those e-machines hoping to get one for like $350 eventually spent an additional $200 to $300 bucks easily. As you can see there might be a profit of something around $0 to $200 just by selling that computer alone and then up to $300+ with those accessories or extended service plans.
