If you and your family are on a budget or you have a child who likes to create, why not make your own Valentine cards? You can use ideas from below to have a clever phrase (this works best for the older kids). If you have a younger child, there are websites where you can print off pre-made Valentine cards. For example, I just found Go, Diego, Go! cards on the Nick Jr. website. Remember though, sometimes the ink that you use to print something off is equal to the price or more than the price of what you can find in the store!
The thoughts and ideas on this site are not always mine, but I try to give credit where credit is due. If you see something on here that I forgot to link to, please let me know so that I may be fair to others. Thank you!
