Do you use the plastic buckets for purposes other than organizing your bricks? We have several bucket sets like #5560. 

Now that our collection is growing, it's becoming harder to find what we need in the buckets even though we have them sorted by color. Plus they are in a rather tall, wobbly stack in a corner and they keep getting knocked over. 

So I'm thinking of organizing the bricks into small drawers and getting rid of the buckets entirely. But that leaves me with a million ugly pink and blue buckets that have no purpose. 

I'm big on repurposing items rather than throwing them away. So tell me: what can I use these buckets for rather than storing LEGO bricks?
Well the buckets themselves have value.
If you can't use them you could sell them to people who want them.

Your example set #5560 has an original box only listing on BrickLink, as do many other of the brick boxes, run a search for "brick box" you'll find lots.

The prices vary from a few dollars, to ~$20 for you example. They don't seem to be big sellers, but there are some sales.

If you have a lot of them and/or you want them gone quicker set up an eBay listing for all of them.
