Saving and reusing plastic bags is such a basic tip that we hardly ever feel the need to mention it, but storage is always a problem. Personally, we have a cabinet that is sort of overrun with these rogue saved bags, and it annoys us to no end. Occasionally, we flip out and get rid of them. Curbly suggests making a plastic bag keeper out of a plastic bottle and some string.

As you get them, shove bags in the top hole; as you need them, pull them out of the bottom hole. (I fit 15 medium-sized bags in my bottle.) Having the plastic bags at hand-my keeper will be hanging by my back door-should encourage reusing them. Plus, they look a lot neater packed in that bottle.
