The only time that I ended up going into Best Buy over just ordering something off of Amazon was when I found that they would price match an online Amazon retailer and was capable of buying something at nearly 65 to 70% off. But I was capable of having it directly delivered to a store where I didn't have to worry about some porch pirate taking off with something that had a general MSRP of like 1,500 bucks and was capable of walking in looking at an inspecting it and deciding whether or not I was actually going to take delivery of it cuz if it was damaged for the Box had been dropped or anything like that I was going to refuse it on the spot and tell them to get me another one which isn't something you can do when you order off of Amazon.
I also used them to price match a TV that was on Amazon that they still had sitting on the shop floor got it Hefty $50 off on that one but it wasn't anywhere near what I got off for the new amp/source that I ended up buying.
