When I first started saving money, retailmenot.com  was one of the web sites I began using. This is the PRIMO coupon/sale code web site for stores in my opinion.
When you go onto the site, there is a search box in the upper right hand corner. Put in the name of any store or item you would like to buy and hit search. Anything that matches your request will pop up below. (I just typed in “flowers” and quite a few matches popped up).
By clicking on those matches it will show you two things: any coupons that you can print to take into the store AND codes you can use if you shop on-line! So, if you aren’t into the printing coupon thing, you can just use the code on the internet. Often there are codes for free shipping and significant discounts, especially as we get closer to the holidays.
So, if you are planning on buying something anyway, take a few minutes to stop by retailmenot  and see if you can get an even better deal! Write down the coupon code and head over to ebates  (more about this site tomorrow) to get cash back on your purchases!
