Is there any where else I can buy pods besides from Nespresso? Do they ever have deals?
There are also a lot of 3rd party pods for the Original Capsules. I have bought pods from Lavazza, Bestpresso, and Cafe Joe over the years. If you get them on sale you can get them for as little as $0.30 per pod.
Trader Joe's also has it's own brand of capsules, I believe it's $5 for a 10-pack.
Finally, both Starbucks and Illy have recently produced their own original line capsules as well - but those tend to be inline pricewise with with Nespresso.
... edit....
I just saw you were asking about a Vertuo, and I believe that Nespresso patented those in a way so that you can't legally make off-brand capsules
All of the above mentioned pods are O-U, with the exception of Cafe Joe which is Badatz (I haven't had starbucks or illy, but I believe that they are O-U as well).
