Bigger is NOT Always Better

I have a love/hate relationship with bulk warehouse type of stores. Certain things are, certainly, cheaper when you buy them in mass quantities. But a lot of things are just bigger. Not cheaper.

There are a few things I've purchased in bulk because the bulk price was a better deal, but it's taken my family jokin' FOREVER to use all of it up. The cheaper price doesn't justify the use of shelf space in my already space-challenged kitchen.

Some of my bulk buying boofs have been popcorn kernals, canola oil, and pancake syrup.

What say you? What have you purchased in bulk that you wished later someone had knocked some sense in your head before you bought? Are there items that you think really DO make sense to get in a larger quantity?

Inquiring minds (mine) want to know.
