That is correct 1% on purchase. Unless they are running a special, which has happened already.
It is great to start in a year before I left I was able to get 250 reward points which is equivilant to $250. You receive it on a debit card. I was able to use it to purchase some of our meals. Almost like getting free money. But remember use cards sensible!! If you don't have it to spend don't put it on the card. Their are other stipulations also if you read the site being late for payments etc. rewards are unable to retrieved.
