Only during the last day would you get any major discount. Of course, that is if there still is stock left. I only go to scout for good deals, and if have, wait for last day.
I would suggest getting a desktop, but even so, you might as well build your own desktop. For laptops, you should weigh your needs. More portable ones usually sacrifice performance, while those powerful ones are heavy. Find out your needs, requirements and budget and weigh the best option.
