I looked at the terms linked in the article. It appears these terms are attached to special purchases from Apple solely for promotional purposes. (i.e., you contact Apple beforehand about buying some for a promotion and they give you a discount). In that case, you are accepting the contract. And it's not like they'd sell you 249 iPods then get pissy because you had fewer than 250.
But, I believe that if I buy an iPad at retail, I can use it in whatever promotional capacity I see fit as long as I do not violate Apple's IP.
In short: nothing to see here, move along
If you mean the guidelines then no. There is no mentioning of rebates. The following is a excerpt from apple's third party promotion guidelines as of the date my posting.
Purchasing Apple products. You may purchase products for your promotion direct from Apple (via an Apple Retail, Online Store, or Telesales representative) or from your Apple Authorized Reseller. Visit http://www.apple.com/buy for more information.
It simply says that you may buy your promotional material from any authorized source. A cursory glance of http://www.apple.com/buy reveals nothing. There is rebates mentioned on this site however, which might have been what you presumed was related to this, however they are for mail in rebates and so forth offered by apple themselves.
