Samsung Tab 8 Ultra + Tablet recommendation

On Amazon, tab 8 ultra is being sold for 400 to 450€, which looks too good to be true. Can anyone please verify if it is a fake deal or not? It is a third party seller so I want to be cautious.

Also I had a question about the tablet. I am a student and want tablet to primarily take notes, annotate pdfs, and maybe watch video lectures. I was thinking between tab 9 fe, s6 lite, or one plus pad for temporary and then buying a better tablet in Black Friday sale. Which one should I go for, or if you have any other suggestions, please let me know. I am checking through unidays as well for better discounts.

Best regards!
