[Attention Surplus Disorder]

I see they were a dime cheaper (10.10 vs 10.20) on the particular Country Life D3 5000 U x 200 pills *but* would end up more expensive due to shipping ($5 vs $2) If you were buying more items at one shot & could take advantage of their “one price” $5 shipping deal, go for VitaCost. I was *only* shopping for the D3, being otherwise well outfitted, and I knew the $2 shipping from iHerb was in essence unbeatable. In general, I would suspect these outfits are very, very competitive. I mean, very. I only price compared that single item. I’d be surprised if shipping and sales tax were *not* the biggest cost-difference items on a multi-item order.

I'm working on a spreadsheet -- of course, with all the variables (size / brand / dosage / supplier / e-vendor / Natural Products Association-GMP certified), it won't be anything more than scratching the surface.

I will compare Amazon, iHerb, Swanson, and Vitacost.

Details later.

Cheers!
