I have been a major Swagbucks user for a few years now. They currently have a great promotion to earn 800 Swagbucks and you can get a box of free stuff (includes two fan-favorite beauty products and three nail polishes), 800 Swagbucks = $10 Amazon.ca gift card.
Swagbucks is a search engine which rewards you with Swagbucks (their currency for points) for searching. You can use it for searching and you will be randomly awarded Swagbucks for searching, usually around five to 10 Swagbucks once or twice each day.
Remember that you can cancel anytime but I suggest waiting until you receive your first box (my wife really liked her first box but we both felt they were overpriced each month to pay).
Even with all the various ways Swagbucks gives you to earn SB for gift cards, there are few that give you this many SwagBucks in addition to new nail polish and make up, so take advantage of this valuable offer while it lasts!
Please note this offer is available to new Julep Maven members only. Shipping charges apply to receive the Julep Maven box (it cost us $3.99 for shipping but we cancelled after the first month).
