I wanted to SE a GPU so i ordered it from my main account, and a PSU from another account. On Amazon, They were the exact same weight. However I received both today,
and the GPU package is 2.4 kg and the PSU is 1.2 kg.

Does that mean I can't do the Wrong Item Method ?

The PSU Is half the weight of the GPU, so It's obviously a huge variance.

Do I buy another psu that is 2.4 kg ?

Find an Item from the same category that's as close as possible to 2.4kg.

I tried finding an item from the same category, but it's proving to be a challenge. I've ordered a pack of sheets that weight 2.5 kg? do you think that's enough ?
Oh and if you have any idea for the subsitute object from the same category, that'd be splendid !
