TCR -Bonus - System & Shop There is a new bonus system for registered customers by wow-gold-tip.com, the so-called TCR (wow-gold-tip currency rabatt) bonus system. Registered customers do receive TCR´s for specific products they buy. The TCR´s will be collected on their accounts and are comparable with virtual currencies. In our TCR Shop the TCR´s can exchanged to all products in the TCR Shop if you want.
