Rewards ladder is great if you have large source of friends joining. As of right now, I don't have a large enough source of friends joining, but you can ask Redeema about that. He's been using luckysearch/rewards ladder longer than me and has much more credibility for that. As for luckysearch, its probably the best site ive used in a while. You win points at random searches, and you can get amazon giftcards for as low as 500 points. All points won/achieved on luckysearch, rewards ladder, and rewards shopping, will transfer into your superpoints network catalog. Stick with luckysearch, tell your friends about it, and you will win. If anything,the more persistant you are, the more you'll win. And yes,amazon giftcards are sent via email. Its really fast too, about 2-3 days to reveive it.
