Completely empty box? Have you done that before? I had in my mind that I order a few things tick the box so it all comes in 1 package and then say the ram didn't come.

I've done a lot, way beyond this.

Either of the two will suffice- partial refund or the empty box per se. If you opt for the latter, be sure to make a tear on the box that's consistent with the size of the Item (Ram) or just a little bigger. Seal It with a different colored tape thereafter. This will give the Impression as though It was tampered with during transit.
