You can throw a rock and hit a supplement store in this town, but most of them don't have the great pricing and selection as VDN! I'm that person, whipping out my cell phone and price checking everything, and it's actually pretty rare to find anything cheaper even on Amazon.
Selection is pretty thorough- from liquid aminos and PB2 powder in the food area, ample pre-workout and BCAAs and natural vitamins and a whole back wall of refrigerators I haven't even looked at yet. Staff are cool about checking in on you or letting you know where to find something.
Bonus points for having a clearance section (front right corner by the meal prep bags) and offering a sample station to try featured products and flavors to help in the decision-making process. Other reviews indicate that they give out free samples at checkout, but so far I haven't seen any- maybe they discontinued this practice?
