Beware of Upgrade Pricing - Don Sykes2
Probably a better title would have been - Be Aware of Upgrade Pricing - I think that's what he meant.Wednesday, October 08 2008 @ 06:48 AM PDT
Beware of Upgrade Pricing - jss
I'm confused by the use of the word "beware" in the title of this post. Beware of upgrade pricing? The poster proceeded to calmly and clearly describe a perfectly normal and reasonable upgrade pricing policy. Nothing to fear. No danger.Reply to This
