If I can't buy organic, I buy frozen - the next best option. I'm quite happy to be able to buy shredded onions, peppers, etc. for 4 lbs/$5 from Safeway. Unfortunately, no markets out here in DC. But back in Vancouver, it's a lot cheaper to be Vegan.

So far my groceries are literally about $40 a week - a $70 difference from when I eat dairy or meat products, with lots of starches and fats as well. No complaints here! I feel way better. I haven't gone completely raw vegan yet, as I do like to have a cooked lunch. I juice a LOT of my food. I also love Odwalla, that makes organic, not-from-concentrate juices. Some of them have added sugar (natural sources), so I steer clear of that. The Super Green and Mango Tango are awesome. You can pretty much find them anywhere, if you're on the go. They have them at Starbucks too (which are everywhere)!
My meals are looking something like this -
morning - as many fruits as I want up til lunch time - usually 3 bananas, couple apples, some in season fruits, some fruit juice (mango)
lunch - huge salad for lunch (spinach, lots of different fruits and vegetables)
snacks - lots of vegetables and fruits toward dinner
dinner - big salad or spaghetti squash with marinara sauce and raw vegan rice protein powder as needed (usually after workout) - may drop the protein powder soon as it isn't really needed I find with the mass amount of vegetables and fruit I eat, my protein intake gets surprisingly up there!
I have a HUGE amount of energy, which is making my workouts kick ass. Jump squats have never been easier, haha. I should mention I eat low-fat vegan as well; I don't really eat nuts at all, except the occasional treat. I do eat hummus most days to get some in, but I find that through all the bananas and avocados I eat, I get a decent amount.
My strength routines are high intensity 3 days a week and lower intensity 2 days a week. I don't do standard cardiovascular exercise, as I am a dancer - so about 30-40 minutes varied intensity 5x a week.
I should also mention - I had some cystic hives left over on my neck/jaw from when I accidently ate some dairy. They have completely healed up since I started eating 80% raw - when they usually take weeks if not months on an omnivore diet.
