If I were on a tight budget and didn't have a prescription, I'd definitely get mine from Amazon. It's a relatively cheap, generic product. I'd be a little worried about other unexpected chemicals being mixed in, but food is probably even more of a concern in that regard. On the scale of things to fret over if you're short on cash, vitamin D sourcing is probably pretty low. Besides, what are the chances that a local store's vitamin D is actually higher-quality? It wouldn't surprise me in the slightest if they both ended up coming from the same place.
