I purchased 2 of the NEC 15" LCDs. Both were open box and I submitted my rebates with the clearance shelf tags and proof of purchases. The rebates are both valid. Here is an example of one:

I purchased Monitor #1 for $129 after receiving an open box $50 discount from the manager, $20 off 100 and napped the rebate. Final price $59 plus tax.
For Monitor #2, I bought open box for the $179 price, filled in a jumpdrive to get over $200 and used the $50 off $200 also napping the rebate so $179+40(jumpdrive)-20(jd rebate)-$50off-50(nec rebate)= $99 plus taxes. Thank you OP!! and good luck on your rebates!!
