But that's not accounting for vouchers given by lenovo to extend your warranty after receiving the laptop. (15~20%)

So the margin could be lesser in the end.

It's complicated but here goes.

If legion 5P max spec extend now vs extend later for 4 years Legion Ultimate Support, price is same in the end. Could be lesser if you extend upon receiving if you use the promo code to reduce the warranty add on when you receive the laptop.

BUT

If legion 5P max spec downgrade to REGULAR ONSITE 4 years vs 4 years Ultimate Support, price diff is about 130+ cheaper if you downgrade.

Get it?

I prefer on site because they can immediate fix stuffs instead of waiting for parts.

To each of its own, but do consider parts shortages are quite serious currently.

You don't want your laptop to sit at a center for a prolonged period esp during this era.

yes, you can. But the price will be at regular price, higher than you order time.
