Is there a way to find any unused Meh-coupons?

I kinda remember “winning” some coupon code(s?) during the multiple contest period put on by @Chadp and others. I don’t think I’ve used it/them… How can I verify?

I was gonna buy the SmartSurge, started looking for a coupon code, now it’s sold out. Yeah, I know only $5 off but it’s the 2nd time this happened so…is there a way?

Thanks
