I don'y have a dog in this fight, except I have been buying from Sam and the boys for a long time.
The market has changed a lot over the years. In the early 2000s you could buy product in bulk powder that was awesome. NP (along with BN and later SP) did very well in this regard. Sadly, the prohormone powder availability dried up. That was sad.
The same thing is happening with other (non-PH) bulk products. They are harder to find, and must require a large initial investment. NP still has some, so does SP.
All in all, Sam's team does a great job. Like any retailer, I cannot expect them to be the lowest on every item, or to stock every item. Look, for example at the size of NP against Vitacost or Swanson (for staple items). The later two companies are huge, but NP still maintains similar pricing on most items.
And for boutique items, there will always be a need to go to another supplier (like a medical or scientific company for bulk potassium nitrate).
All in all, Sam (who LOVES GARY COLEMAN, and many believe is actually Coleman's twin mistakenly separated at birth) is a go to for me. About the twin thing, admit it - you never saw Sam and GC at the same parties at the same time; did you? Coincidence - I think not.
Enough butt kissing.
