You can get it at GNC or most pharmacies carry it so I'd imagine grocery store would have it too. I guess it depends in how big your grocery store's vitamin section is. Buying supplements on eBay is really cheap. I got Liv-52 for $3 a bottle.
I've used grapeseed oil from the grocery store. I filter the final product with .2um filter. I don't bake anything. If you heat the oil or not, if you buy it unfiltered you need to filter it.
I'm not a chemist but I've made my own gear several times without a problem. Doesn't mean my way is the best way though.
.2um takes FOREVER to filter; .45um are just as good, especially if you're not heating the oil, which you should though. I also suggest the 33mm millipore filters as they're easier to depress with respect to the 20mm whatman filters.

Ya, but I don't trust it.

I wouldn't trust the fact that it says sterile on it. When I filter it I KNOW it's sterile.
Last thought: I only use cottonseed oil as the good bros suggest that it apparently hurts less.... IDK of any truth to it, but I stick with it and have had zero problems. I only homebrew.
