Any TV that sells that cheaply is probably crap, unless that same exact model is available somewhere else for more regularly. Like others have said, they make special crap models for black friday that aren't worth the discounted price. There is a reason that they don't sell them year round.
Recently, I bought a new TV. I wanted to have one in the basement for gaming. Originally, I was going to buy a 32" TV. After doing some deal shopping, I ended up with a 50" TV (don't facepunch me yet). I bought it from Dell. Total cost for the 50" TV with 120hz refresh was $614 delivered, BUT it came with a $300 Dell credit. They got rushed with orders and it was backordered. When I asked why my delivery date kept changing, they gave me a $50 refund. Then I was looking online and saw that my electric company has a $25 rebate for energy star TV purchases 50" or smaller. Total cost for the TV after the $300 credit was $239. I was planning on buying either a PS4 or a new gaming PC, and both can be bought from Dell (on sale) so getting the Gift Card was worthwhile. The TV was a name brand (LG) current years model. I bought it in August of this year. You can get good deals year round. Don't settle for garbage.
Yes, I like to game. I try to do it as cheap as possible, and I've been very successful at that. I've mainly been using a PS3 for the last 7 years, and I buy my games cheap. I'm normally at least a year behind the current new games, so instead of paying $60 a game, I buy them (or get gifted them) for $20 each. For short games, I'll rent them from Redbox 2-3 times and pay a grand total of ~$5 assuming I don't have free rental codes. That works best for things like "Last of Us" that are fun but crazy short.
