Sometimes people come up with genius ideas. This is one of them.
Punch a hole in all of your gift and rewards cards and keep them on one key ring to save space in your wallet. Bonus Tip: alphabetize them so they're easier to find. Bonus, Bonus Liz Tip: write down any expiration dates (if there are any) on your calendar (or "phone agenda", Marla) so you don't get screwed over.
I guess this idea would only work well if you're a woman and you can carry this key ring around in your purse? I don't know a man who'd want this beast amongst his precious keys. Do men even use reward cards? Is that a sexist thought? I really don't think they do. I've signed my boyfriend up for at least four different cards and I'm pretty sure each one is passively mourning their fate at various garbage dumps.
I heard this tip from the site Cooking at Cafe D, so obviously their page is now in my bookmarks. Also, to the people who are about to message me and go, "Hey, there's an app for that" - don't get smart with me. I'll cut you.
