Yes, I'm well aware of the methodologies used when boxing.

In terms of "filling with sand", It's futile If the company checks the package on receipt.

One of countless examples (and stating the obvious), Is If the Item Is light enough to not register a weight on consignment, then dry Ice Is not required when boxing.

Ah right, that's another obvious one. I'm thinking also during the winter when it's colder it's not as suitable unless shipping by ground and very far away.

you could put the dry ice inside the package and say that you were wrong to make the order ... so they shouldn't check ... this method had recommended me @mothered to change the broken ps3

Did you try it out? If so, how'd it work out?

not yet ... but honestly with ice I don't think to try ... as soon as I have the money I text the ps4 replacing it with the ps3

I always try to advocate learning how to SE instead of refund when you don't have the funds. It requires no investment, though it is a bit more work than a refund.
