Computer and printer buying headache from OfficeMax

So, I see a good deal on a laptop computer and free printer after rebate from OfficeMax in the Sunday ad, and I'm sold. On Friday, I visit the store in Roseville, and they don't have it in stock, they say try buying online. So later that night, I jump online and put it in my shopping cart. Next, I find the HP 3915 printer, and try putting that in my shopping cart. Nope, they don't let me buy the printer, I see an error message: 21020985 This particular item is not available for delivery in your area. Please choose another item. If you need assistance with your selection, call 800-283-7674. No big deal, I'll just go pick one up at the store in the next couple days. So on Tuesday, I head over to the Brooklyn Center store and buy the printer. Today I find the HP printer rebate info and print the offer. Right in bold print it says: Good only on same day purchases. What! I wasn't able to buy these on the same day, because the online store wouldn't sell me the printer. So I call HP's 800 number, and they tell me nothing can be done, try working with OfficeMax. Ok, I get on the phone with OfficeMax, and they also are reluctant to do anything. I haven't lost my composure yet, and kindly ask to talk to a manager, and they connect me with OfficeMax executive resolution group. The woman there is now trying to help, more to follow...
