I don't get what is going on here lately in the forums. Every time there is a rebate somebody whines about it. I have never, repeat never failed to recieve a rebate in the last 3 years.
I will openly admit that it requires some work on my part... I keep a spread sheet of the product bought, store, purchase date, rebate phone#/website and rebate amount. I also make copies of my upc's and rebate forms on my scanner. Then I wait. If I get a rejection I call up and complain and always get my rebate.
I have never had a problem that couldn't be resolved with a phone call to the rebate center, even with two rebates for one item.
There is one universal truth regarding rebates: No matter who you call prior to sending in your rebate request, each time you call, you will get a different answer regarding that rebate, because nobody really knows anything.
Your best bet is to submit both, as advertised, and see what happens.
