You can get samples and small (1 oz) trial sizes at ebarbershop, You can also get single $6 bottles with free shipping through the Amazon Marketplace (I don't understand why so many use Drugstore.com when you have to have a certain sized order for free shipping).
I use Amazon often. Sometimes you can get there much better deals than on eBay. Thanks.
