I was just curious where other DVDTalkers like to buy their DVD's and Blu-rays from online. I used to buy from DeepDiscount a lot, but they really went downhill a few years ago. Now I mostly buy from Amazon. What are your current preferences site-wise?

Amazon

Buy mostly from online retailers when they have good sales

Amazon mostly
Fry's(had some good deals in the last few months)

Sometimes
Deep Discount(Never had any problems with them.But maybe buy from them A few times a year,if at all.
Gohasting(used)
Ebay(used)
Shout! Factory
B&N(Criterion sales)
SAE
Best Buy(I'm about done with them though)
Target

Outside USA(Other regions)
Amazon.uk(Box sets mostly)
Zavvi
Arrow
One order from Amazon.de(Germany)
Had to buy The Wanderers [Blu-ray] [Limited Edition] + some
other blu-rays not out in USA.

But I'm changing the way I buy movies/TV show,starting the last few months.
going to go more digital codes and streaming.Already have Netflix and Amazon
prime.

And just buy Limited Edition sets that interest me.And when stores have great sales.
Just to many movie/TV shows available these days.And my physical media collection is to big already.

ImportCDs often has the best prices of all.

Wherever it's cheapest. But mostly Amazon and Best Buy.

How do you know when you buy from Ebay if it's real or fake?

This

Nearly all Amazon but Amazon.uk for some boxed sets and a few things at Twilight Time and Warner Archive.

You don't, but that's why you buy from reputable sellers, ones with a lot of positive feedback.

Amazon - Rarely these days, they just don't have the best prices anymore for most BDs.

DVDPlanet - Their website has none of the quirks or flaws of its sister site, Deepdiscount.

eBay - New releases can be had cheaper on eBay a couple of weeks after release than other places.

Best Buy - Occasionally, though it is mostly driven by one-time sales.

Amazon.co.uk - Mostly for imports and large box sets that end up being far cheaper than American versions

GoHastings - Almost entirely for used discs, though I really don't consider them an option anymore. The miniscule savings are not worth the gamble one takes every time with GoHastings' filthy used discs and slow shipping speed.

Rightstuf - This anime retailer doesn't have the absolute best prices but they package things immaculately.

Blowitoutahere.com - I would never order a rare, hot item from them, but for everything else they are fine.

I buy about 90% of my Blu-rays from Amazon.

I'll jump over to Criterion's site (or Barnes and Noble) for Criterion sales or FoxConnect for Fox sales, etc., but Amazon gets most of my Blu-ray dollar.

I have used Shout! from time to time for exclusives (like the Halloween set + lithograph) and occasionally use Arrow for Region 2 imports.

BN.com
Foxconnect.com (they often have excellent deals)
Deepdiscount.com
Half.com
ebay.com
gohastings.com (used to buy a lot more from them)
bestbuy
importcds (don't buy as much since they raised their prices)
Amazon.com
Amazon.co.uk (I think I've bought more from .uk than .com this year)

I'd buy from these vendors, except that they have some absurd shipping rates to Hawaii:
