I like being able to send my friends cards without having them come into town! It's easy for us, as we're in different cities/states. We can't always go out together which is great because it saves gas money too!! Sometimes they don’t get there card right away so you have time but sometimes if your friend gets their card immediately after sending yours then that could be an issue? Not sure how this affects other people though haha. Also, with monthlycards you never know what kind of month (or year) will end up coming around again until its already here :) So far i've had no issues or complaints about our experience using these services. Sending fun birthday invites has been easier than ever before thanks to yearlycardz. The only thing was when one person got sick at his house he couldn't use all those awesome features :( But overall everything worked perfectly fine from me personally knowing someone who used it once years ago.
