I am helping a friend upgrade her laptop.  It currently has a single 4GB SO-DIMM, DDR3 PC3-1333Mhz module, and I'm looking for a compatible module to add into the spare slot.  Looking on Pricespy a lot of places appear to be out of stock.  I've found one on Trademe but wondering if anyone here on GZ has a spare stick of RAM they want to unload.

In Palmerston North, for shipping purposes.
