I'm trying to get a new laptop (well, used but you kno what I mean)

anyway, there's a couple I'm watching, and doing a bit of research on them, I noticed both the sellers registered on 12 Nov 2004. 1 seller has only 1 feedback (positive) and the other has 2 feedbacks (both positive). so I looked at the feedback of the buyers.

The guy with one feedback, all the feedback of his buyer is positive, but every item is a laptop. And every seller that guy bought from is fairly newly registered, and only has a handfull of feedbacks. What else is odd is the other one is very very similar.

Other odd thing is looking at these buyers feedbacks, the last bunch of laptops bought finished on Sun12 + Mon 13, yet they left feedback about great delivery and excellent item etc only the next day. Okay I understand you can get next day delivery for your £25, but how if it finished at 9pm on Sunday would you be able to leave feedback about delivery at 9pm the following day? Surely thats same day delivery and would cost a lot more...

It's a bit confusing to read but hopefully you follow me, just wondering whats going on as it is very odd, not sure if it is a scam
