I save bottles from microbrews that I bought at the store, clean them out, and put homebrew in them. I've been saving bottles like this for months and now I have hundreds of bottles that I reuse - some have been recycled three or four times.
If you don't have enough bottles, maybe talk to a local bar and see if they will let you dig through their glass recycling bin. Or ask friends to save their bottles for you. I have some neighbors on my street who drink microbrews and they are more than willing to let me rummage through their glass bin the night before recycling day...as long as I let them try my homebrew when they come visit
