Organizing my supplies really helps me spend less.
I also LOVE Evernote. I've got all my stamp sets, dies and any cards kits all in the app. When I have a few moments I'll browse through it and find things in forgot about, or a little stamp image I can use in a different way.
Plus if I see a leaf stamp set I need to have, I can just type in leaf and see the leaf sets I already own. Helps me decide if i truly need it.
I'm gong to try and commit to $50 a month...but more importantly I'm going to actually MAIL out some of these cards I'm making!!
