I purchased three different size compact flash memory cards through Amazon.com based on a link on Spoofee. A 128Meg, 256Meg, and 512Meg. Each had a rebate totalling $45 or so. I mailed in everything and Viking sent back therir customary "you are missing the receipt and/or UPC code'. I RESENT copies of the original paperwork which included the Amazon.com receipt and UPC codes. Still haven't heard from them and I bought these way back in January! I guess I got screwed. That's the last time I will by Viking products.
