There is basically no way to get credits or promo-credits FREE without doing anything in return. So check out this site http://www.myyearbook.com/ When you complete an offer (It could be anything from simply watching a video to downloading something) it gives you something called Lunch Money. Once you get enough Lunch Money, you can exchange it for imvu promo-credits. 100,000 LM gives you 500 promo-credits. Oh yeah! And simply creating a MyYearbook account gives you 500 imvu credits just like that! Done Deal.

Regular credits are better than promo, because when you buy something from the IMVU catalog, the amount is subtracted from your regular credit balance. You can only use your Promo credits when you don't have any regular ones. To get regular credits, go to this site: http://www.metarl.com/register.php?refer… it works 100%. Just register, and you can earn credits for whatever game you want (including IMVU)

To get Promo credits, go to http://www.imvu.com/earn/credits.php and click on an offer.
