A:
Doubtful. BestBuy has recently significantly (over the past few years) shrunk their pro audio stock and completely eliminated in-store availability of items in the aforementioned category.
Select retail locations used to have wide selections of recorders, microphones, instruments and the like and the website had an wider selection. Back then pro audio items went on sale all the time. Unfortunately, as the company has chosen to delist the majority of pro audio items and sell a very limited selection (and stock) of products online you are highly unlikely to find a sale, unless you get lucky and find the H2n on clearance when Zoom discontinues it (by which point you probably won't want it).
BestBuy puts items they want to highlight (because they are hot sellers), occasionally new items and items they want to get rid of (either because they're going to stop carrying it or because the manufacturer is discontinuing it() on sale and unfortunately the H2n doesn't fall into any of those categories.
I actually made out like a bandit buying a lifetime worth of clips, clamps, adapters, XLR, RCA and other cables as BestBuy was delisting them, but the last time I got a recorder on sale was several years ago when I bought my first H4n and H1 (I have since gone through a second H4n and H1, two H6s and an H5) and paid full price for all of them (I work in broadcast journalism and am rough on my equipment so I go through them rather quickly and always carry a spare).
if you are looking to save money on the H2n find a lower price and use the price match guarantee.
