Just to add, I called this store many times checking on stock and they kept saying they only had three 8 gb units and after many days of this I decided to drive down there and just buy what they had preached to me about what was in stock 
Thats my luck and now I am 

After 2 weeks of calling and driving and emailing and only answers I got was you will not find one.
This is their mistake not mine. If I bought a 16 gig on eBay it would be 330. Or higher

I got unexpected surprize 
Yesterday I purchased a 8 gb Nexus 7 from local store that had only 1 left and I could not wait for a 16 gb.
After playing with this tablet for 10 hours or so I started to explore in details and to my surprise it is in fact a 16 gb and states so on the box in the code- 1b/t30l/16/1g/v

They had trouble scanning the sku numbers and did in fact take 5 extra minutes getting the thing to take and when I paid for it I was happy that I settled for a 8 gb version but now it seams to be 16 gb
