Need a print screen from an "old" webpage

[Caple]

Hi there.

I recently bought something on the web and I was pretty sure the guys put the wrong price on their website.
I bought with a Visa card (it was on thursday) and the order is still being analised. I'm sure they noted the error and froze my order. Because they already changed the website.
Unfortunately I don't have a screenshot of it, and couldn't find a cached html or whatever on my computer.
I visited the site at work also and I intend to check it there tomorrow.
Any clue how can I check it to make a screenshot?
Maybe offline browsing or something like this.
I use Firefox.
Thanx.

Screenshot wouldn't help because you could compose anything you want locally and take a screenshot of it.

Most merchants reserve the right to correct pricing errors.

I know this thread's a month old... but did you try Internet Archive?

Maybe type in the specific URL for the product and see what you can find? Not sure if it will hold up as "proof" but it's the best you'll probably get.
