Today I only have two to share so here it goes!
1) skip the shaving cream and shave your legs with cheap conditioner. You can literally buy a big 'ole bottle of condition for $1 at the dollar store and though it may not do great things for your hair--I've learned it works great for shaving legs! And, it's waayyy cheaper than shaving cream so unless you have ultra sensitive skin I vote go with the conditioner.
2) buy bananas in bulk. I have a smoothie about every day sometimes twice a day--that said I go through bananas really quickly. Of course the day I buy extra bananas is the day I slow down on my smoothie intake and they end up going bad. I found a solution by cutting up ripe bananas and freezing them! The frozen bananas work great in smoothies (and if you blend up a few chunks of banana and some milk you get a healthy "ice cream"!) and when frozen they don't really go--though I haven't exactly experimented to see how long they last in the freezer! Oh! And another plus to cutting up and freezing your bananas is you don't have to eat a whole banana you just grab as many banana pieces as you need. 

That's all I've got for now!
