I am pretty sure that almost all of Niagra's items come straight from QBP. At least, anything I have wanted from there comes from Q. So probably they have a feed-through to the QBP catalog to see if it's in stock. This fits with them taking a very long time in comparison to most online companies and also the pricing is consistent. There have been very few instances where they have had something I couldn't get faster and cheaper from my LBS. Nowadays, anything from QBP is at my LBS the day after they order it, and they order multiple times per week.
