Is soap better than Amazon in your experience? I'm a heavy user of amzn for a lot of this stuff, but hadn't heard of soap.com.

Actually Amazon owns soap.com. It's a more limited inventory but quick (1-2 days typically for most items) with free shipping over $49. I supplement soap.com with amazon.com as needed.

Soap.com is a Quidsi company which is a unit of amazon.

Meh, you can't cruise soap.com on a Saturday and fill-up on free samples ...

I really, really wish costco didn't give out samples of anything.

Each sample cart becomes the nexus of a swirling shitstorm of carts and kids, all oblivious to the people who are trying to get some shopping done.

Try finding a Costco Business Center near you. You don't need a business membership, and they don't have samples or the food court that creates all the commotion.
