Any ideas on seing gpu's?

Wrong item received could work.

I ve been thinking of that as well but how to get away without returning it.

What you can do is box it via adding books to match the weight of the gpu or substituting it with a gpu that weighs very similar. You could also use the did not arrive method.

Better yet you could just use the same battery acid leak excuse. I find that it works with any electronics 90% of the time. What you are trying to exploit using the leak method is that they do not know enough about electronics/pc parts to disprove your claim so 90% of the time they will buy it.
