Quoted from phillymadison:What was some of their past deals? The current one (buy one and the 2nd is half off) seems pretty good.
Their old deal was buy 2 get 1 free, now it's buy 3 get 1 free. I'd be tempted at the old sale price to try 3 sheets, but since PDI is obviously better without a substantial discount over it I don't see the point.
I'm sure that price on 12 sheets is from the old Invisiglass deal, not PDI. 8 * $295 = $2360 + 4 sheets free. That would be an insane price on PDI. Does PDI ever go on sale? I vaguely remember one sale ever, and it was like widebody only or something.
