(Taken from my post on DVD talk)
The Trade two for one deal blu ray has been changed in the last year or so, the two blu rays have to have a trade in value of $3 now, not 4 in order to qualify for the deal, though with values plummeting the last time I went in with about 8 blus, I only qualified for one new release. I have literally every worthwhile new release on reserve from no until the end of the year: Spiderman, Ted, Brave, Dark Knight Rises, Nemo, Expendables 2, Bourne, The Watch, etc...etc. These titles in most cases essentially cost me only $2 each.
Another good tip, if you are bringing in a lot of dvds, they have the 4 for 1 new release dvd deal going on, the trick here is for example you trade 4 titles all worth $1.50 each in, thats normally $6 credit... but you get a new release and immediately trade that title in, $12 without MVP discount card, $13.20 WITH card. You do need to be up front and check those trade in values though and qualifying titles. Most workers need to be reminded about the trade in deals, I had 4 qualifying dvds the other day and the guy neglected to mention it because I buy only blu rays, I essentially squandered about $7 in extra credit as I didnt want to wait an EXTRA 20 minutes for him to correct it.
ALSO, those of us that take advantage of the upgrade and save, be sure to check those trade in prices, I've had titles trade in for a little as .06... yes six cents! For that I am much better off trading THOSE titles into Best Buy during the next U&S. If the title I trade in is worth under a certain amount, I tell them to pull them for me.
You CAN upgrade your blu ray reserves to 3D, just have to pay the difference, which is generally under $5, I usually
The discount card $15 for a year is SO WORTH IT, you are getting 10% extra on trades, 10% off used titles AND you get a year of Entertainment Weekly, which it is worth it for alone
