Shop around at authorized online and retail resellers and you will find a better deal for the non-upgrade price than Adobe offers for the upgrade price.
My favorite online store is B&H in New York. As a single state retailer, they (legally) don't have to collect sales tax in most, if not all, other states. Secondly, this is the time of year for discounts. It won't get cheaper. It is likely to go back to full retail soon.
Premier Elements 15 is $70.
For $19 more you can get the combo with both Photoshop and Premier Elements.
Thanks for the ideas all. However, it's only 69.99 straight from Adobe right now, so I was hoping that with an upgrade price it would be even cheaper. I'm not seeing it any cheaper than $70 from anyone online, so I was hoping to take advantage of an even cheaper upgrade price straight from Adobe, I just can't find it on their website.
