I visited my local Saturn (Stuttgart, KÃ¶nigstraÃŸe) today to find out they have Verbatim 8x DVD+R DL on sale.
The 10 disc cakebox can be had for as little as â‚¬ 9.90.
All stocked units are Made in Singapore (to my knowledge).
It may be worth to check your local Saturn.
Keep in mind that even most online stores still charge 1.5x as much for the Verbatim 10 pack of 8x +R DL.
