Just a word of warning...I cashed in some of my Pigsback.com piggy points for a cdwow.ie voucher. The link that Pigsback sent me to cdwow had all the cds and dvds priced €1 more expensive than in the 'normal' cdwow.ie website. My solution: log onto cdwow.ie, pick out the Cds and DVDs as normal but then redeem the Pigsback voucher as your checking out. A little bit sneaky from Pigsback I think.
You can use pigsback vouchers on any of the euro sites such as the german [broken link removed]
- used to be cheaper and still sometimes is but prices seem to have harmonised a bit
You get piggypoints for going through the pigsback link, how many?? Probably reflects the extra increase in prices..
