How many coupons can you use to buy HP?

I am looking at the following coupon site for HP (http://www.couponmountain.com/HP/HP_coupon.html?source=google_zt3000). There are several possible coupons that could be used to purchase the zt3000 (for example). How many of these are you allowed to use at checkout?

They are:
1. $50 off any customizable notebook over $999 - NB9367 (exp 8/1/04)
2. $100 off any customizable HP Pavillion notebook w/ XPPro
over $999 - NB8218 (exp 7/31/04)
3. $10 off your order of $50 or more on HP - SV2239 (exp 7/19/04)
4. Save $50 plus free shipping on zt3000 and other models
(no coupon code so I wonder if this is the $50 mail-in-rebate)

Is it possible to use all top 3 coupons (total of $160 off) in one checkout OR do you only get your choice of 1 coupon?

You still get the mail-in-rebate regardless of the number of coupons used, correct?

Can you still use the coupon(s) and mail-in-rebate with the Academic Purchase Program (APP) discount too?


Thanks in advance.

 

one coupon only, they are not stackable.

 

100 off a laptop with XP Pro? Can you use that and a mail in?
