Office Depot currently has the TI-89 Titanium for $94.08 shipped + tax. The next best from Pricegrabber is $30 more. You will need to order the calculator plus a filler (I used $0.29 paper clips) to make it over $150 so that you can use the coupon code 56030509 for $30 off of $150. Also use the 1% Cash Back from FW. Finally, there is a $25 rebate from Office Depothere.
The rebate expires on September 22nd and the above coupon code ends on the 9th. If you are really ambitious, you could try to also use one of the other coupon codes from the Official Office Depot Thread to get one of the "Free with Purchase" items.
Trying to add quantity 1 to my cart, it says "Insufficient stock." My zip is 92037. It does say you can backorder 1, but I'm not too sure if the coupons/rebates will still apply.
lostfirefly said: does any know if this calculator can handel the "del" (d/dx, d/dy, d/dz) operator?
I have to check but I'm pretty sure it does. Haven't used it in a long while. Been using Maple.
Btw, this is a good price for an amazing calculator. I think its a better deal that thatn TI-84 $50 deal. Perfect for all college classes.

Received mine today. It also comes with the USB cable for attaching it to your computer, which I didn't realize.

If anyone is looking still to purchase this for themselves or a family member for school...
The Upromise site has a $30 off $150 OD coupon, (technology excluded) good until 9/30 for members when you shop through their site, since the one listed earlier above has expired.
Coupon works on the calculator if you add a filler to get it over $150. OD considers it "Office Supplies" not strangely, technology.
