If you're behind schedule on your cards, there might still be time for them to arrive in time. If not, a little after Christmas cheer isn't terrible either! :)
You can get 70% off all holiday cards and invitations, through Cardstore. The best part is that they will mail them to your recipients for FREE! In most cases, you will be paying less than the cost of a stamp. It will depend on what the price of your cards is. You can sort it by price, if you want to start there.
Use Coupon Code: CCP2147 before Sunday, 12/17. (Technically, you have until 12:59 am on 12/18. That little fact helped me, as I was desperately trying to get my order in, with a previous deal.)
If you already ordered, it's super simple to log into your account and send another one out. I had a couple incorrect addresses and had to do that recently. I ordered a few extras, but it was still cheaper to have them send them, instead of me. I really don't understand how they can do them for such a low price!
You start at their site, type in the name of the website (Cardstore). Then, you just click to the website and shop as usual. (There are similar sites out there, if you want to search for them, but those are the two I'm most familiar with and use.)
Ebates pays out when you hit $5 (7.5% back now for Cardstore), so I tend to prefer that. But, ShopAtHome is paying out 10% for Cardstore, but they don't pay until you reach $20 and request a check. (Thanks, Dawn!)
