Just a note that those VGC are a PITA but to liquidate/convert. Now, IF you're just going to use them at say, the grocery store, Amazon, etc. fine.
If you want/need to convert them back to cash (ie: Walmart MO or Discover Check Loading) then, IMO, they are a PITA. CAN be done, but I would not want to do $800 of them. Just sayin'
