My amazon account is 3 years old but I never ordered expensive items (mostly books, and small other products)

Has there been Inconsistencies/suspicion raised on the account with refunds or otherwise, at any point?

I want to order it on Amazon, try the DNA method

Find out whether an OTP will be required on receipt of goods.

I would like to use the sealed box method with my old MacBook Pro. Considering that it weight 1.3kg and the new one weight 1.6kg, would it work?

300 grams Is too much of a variance.

Try and match the weight as close as possible.

Also, how hard is it to seal it again?

Not difficult.

You're not working on a schedule, so take all the time you need to flawlessly reseal It.
