@mothered  Correct! Just wondering if this is more efficient than an empty box method? I feel as if costco won't refund/ repalce me because there has been a signature at the given location or will they still go forward with an investigation then replacement?

Yes much more efficient than empty box method. I personally try to stay away from using that unless I have to.
You can SE the PC by saying that the ram and gpu is broken. If they ask for proof, just put in a broken GPU /RAM. I highly doubt that they'll check SN, but if they don't then you got free RAM and GPU which are one of the more expensive items in a PC

Im planning on refunding a pc from them if possible and so will they refund me or replace me if I do a fake signature and say it did not arrive or, would this not work bc there was a signature at the location?
