Apple trying to rip me off?


I received an e-mail from apple today saying they would give me 25$ off any order of 249$ or more... except when I follow the link all the prices are jacked up... when I normally go to the store the iMac starts at $999, the G4 at 1699$, the ibook at $1,299 and the PowerbookG4 at $2199. Following this link though the prices are $1499, $2599, $1999 and $3399 respectively... Is there and explanation to this? I would put the link in the e-mail, but I don't know if that enables others to get into my apple store account. Can anyone explain these price differences?
