I have a Bing Rewards account. Getting one is easy just go here Bing.com/explore/rewards to sign up for a free account.
Then all you need do is go to the Bing search page and do about 30 searches a day. And this is very easy. I found that if I enter say "Urban Gardening" and then click on the image tab it will give me all sorts of pictures BUT it gives me a whole list of links just above the pictures.
The area marked in blue is the "search box" and above it you will see the "images" tab.
On the top right you will see an area marked in yellow. this is you points total.
The area marked in red is "Related searches". Once you enter your search on the bing page and then click the image tab you should get a page that looks like the above. Then all you need do is click one of the related links marked in the red area and it will bring up a new page with new links. click 30 unique links a day and you have your 15 daily points. plus there are always bonus clicks daily that will show up on your Bing Rewards Dashboard.
Why do this you ask? Because you can get all sorts of gift cards. I got two 5 dollar Amazon gift cards and cashed them in on my Amazon account then ordered 4 different kinds of heirloom seeds. All will be delivered free in just a few days. Next gift cards will go for some Red Wiggler worms because I am going to try composting via worm farm.
It takes a bit to get you accounts set up with Amazon and Bing but once you do you can use those free points to buy all sorts of gardening supplies, and all it takes is a few mouse clicks each day.
