Preparing for dinner and dessert

In preparation for dinner I copied down the recipe for my red bean burgers and decided to take a look for any soy milk coupons for my faux rice pudding dessert I'm planning on making. And viola I found 2 coupons for Silk soy milk! (I've decided vanilla soy milk might be yummiest). I'm going to try to combine the coupons if they let me but I don't really know if you can do that since I'm a total coupon noob.
