It finally sunk in that going after $5 Amazon.com credits from Swagbucks is better than going for $50 because although ten times as much, they require eve more points for the bigger credit. No doubt they expect you to use the small $5 credit to cover a partial purchase, encouraging you to buy more.
I buy a bunch of stuff from Amazon anyway, so I expect to use all I get. I've redeemed for two $5 credits. I have enough points for another but I'll have to wait until tomorrow...they only allow two transactions per day.
Looking forward to getting these credits on my account. $10 will cover all the cost of a small purchase including postage, $15 will allow me to get something slightly better. I have 30 pages of bookmarks to choose from.
