It will be extremely difficult to deal Tyranids right now, and if you do they will most likely net only a small fraction of their msrp value. I bought a decent amount of Tyranids with the idea of a second army compliment to my 5K Necrons, as a varietal play and for possible versus games with interested friends who do not have models. I discovered 'nids are total crap in the current environment, especially held up against the consistency of the Necron Decurion Detachment so tried to deal them on three sites to no avail. So, I bought a 28 gallon tote where they will stay in the attic until they hopefully get a bump with the next codex.
